So everyone once in a while when playing a modpack, my game crashed and wont let me back into the world. the message that pops up is as follows: The game crashed: ticking entity Error: java.lang.ClassCastException: class net.minecraft.world.entity.projectile.Arrow cannot be cast to class net.minecraft.world.entity.LivingEntity (net.minecraft.world.entity.projectile.Arrow and net.minecraft.world.entity.LivingEntity are in module [email protected] of loader 'TRANSFORMER' @5b1420f9). if anyone knows how to fix this it would be greatly appreciated, and i dont know which mod from the pack is causing this

I normally only run vanilla or premade modpacks when I host a server, but this time around my friends wanted to make a custom modpack and I've (obviously) run into issues trying to get it to start. Any help is appreciated. Link to debug.log: https://mclo.gs/HEfVtnF

Hello I recently downloaded forge to use a freecam mod and for some reason when i press f3+b to show hitboxes the game crashes. I tested this on other, non-forge versions and it seems to be a forge only thing. I only have freecam by zergatul and optifine in my mods folder. I already tried downloading a new version of forge, and both mods. Does anyone know what's causing this? Forgot to mention: im in version 1.21.8. the crash message i get looks like this: The game crashed: extracting render state for an entity in world Error: java.lang.NullPointerException: Cannot read the array length because "<local10>" is null

Hey everyone, We’re facing a major crash issue on our modded server. My friend built a wood factory using Create, and ever since, he keeps crashing with an entity loading error. "The game crashed: rendering entity in world Error: java.lang.IllegalStateException: null" We’ve already tried removing several optimization mods to test (Chunky, IA Improvement, FerriteCore, FastSuite, Krypton, Spark, Starlight), but the problem still persists. I also tried approaching the area myself and… same result, I crashed with the exact same error. I’m sharing the latest logs here for anyone willing to take a look: If anyone has encountered this problem before or has any idea how to fix it, any help would be really appreciated! 🙏

I am running a modded forge server and am trying to install better end on it using sinytra connector. I have the same exact mods on my client side, and it works fine and allows me to use the better end mod. However, when I try to start the server with the same version of better end and bclib installed onto it, it comes up with this. The server starts fine without better end, but i'd like to try and keep it if it's possible. Any help is appreciated. https://mcpaste.io/340f573a8a524453

I've tried to load mods on two different server sites. I'm using forge 47.4.0 and minecraft 1.20.1. I've looked on different forums and reddit yet no fixes recommended have worked. The logs: https://mclo.gs/c1cSakg

Mods work when I play them as a client, but when I try to start a server with them server stalls, and restarts. I've tried deleting mods (went from 110 to 85), disabling the quark narrator, nothings working. Crash Log Latest Log

I saw someone had this issue and thought of asking for help, since my situation is pretty much the same as theirs. My game was running perfectly fine until I closed it earlier today and when I tried to hop back in this issue appeared. I leave the link to my logs below. https://mclo.gs/acul10C

Problems with somethin somethin Sponge transformer throwables or something i cant understand it im sorry https://github.com/KingDeathClaw/Minecraft-Crash-Logs/blob/main/Ice and fire mk5 epic fight pack crash log 2025-07-29 it has something to do with epic fight mods i added and i cant tell what other mods are causing the conflicts.

I've been having this problem where i want to play a modpack i made but when try to start minecraft it crashes while loading the mods. I will add the crashreport but in the top it says "Embeddium instance tainted by mods: [entity_texture_features, sodiumoptionsapi, oculus]". When i turn off embeddium and the other mods the game still crashes but the crashreport doesn't show what mod is responsible. The description in both crashes stays the same. I've tried to delete the forge-client.toml without succes and also tried to delete the modpack and make a new identical one without succes eiter.

The Weapon Printer is inaccessible, as its GUI doesn't open up after right-clicking it. Also, every gun in the base mod says "This ingredient crashed when getting its tooltip. Check logs for details." when hovering over the item. The latest log is too large (>512kb) to even upload to pastebin, so all I can show here is the error of the item. As if that wasn't strange enough, whenever I break the Weapon Printer and pick it up, it takes a few seconds to show up in my hotbar/inventory. Another strange behaviour I've seen is that after playing for a while, the names of the mods in the tooltips just disappear. (Without F3+H) Any help will be highly appreciated!

I'm playing a custom 1.20.1 modpack and everytime I try to open an old world it shows a screen that says, "Errors in currently selected data packs prevented the world from loading. You can either try to load it with only the vanilla data pack ("safe mode"), or go back to the title screen and fix it manually." Pressing Safe Mode leads to a screen that says, "Failed to load world in Safe Mode. This world contains invalid or corrupted save data." I have tried making new worlds and it's always the same, I'm able to get into the world the first time then can't rejoin it. Here is a log from when I tried to open the world, https://pastebin.com/9wAvHWwL And this is the entire latest log, https://mclo.gs/qkf06Ns

Hello! I was working on my custom campfire tile, and suddenly got a problem. The problem is with the rendering of the item in the campfire inventory. The TileEntityRenderer says that the inventory is empty, witch is strange cause the existing logic for the cooking food works normally. Additionally, when i leave and then rejoin the world, the item renders, but the inventory is not saved really well (could be caused because of the not finished save logic). I would be really thankful if you could help me with this problem! Link to the entire code; https://pastebin.com/tHZ9snN7 I'm sorry if i had presented the post not well organized. It is my first post on this forum, and I'm not sure how to a well structured post. Additionally I would give my apologies for the not well structured code, I had tried to fix it in multiple ways (unsuccessfully). Feel free to criticize the code with good criticism. I am open for improvements.

I tried adding the Create (6.0.4) mod to my modpack which causes it to crash before it finishes loading. I tried removing the mod Cold Sweat because the error said it failed to load due to something in Create but when I removed it, it kept crashing; and I also tried downgrading Create, but nothing helped. I assume there's an incompatible mod that's causing Create to not load correctly, but I can't find it. launcher_log.txt: https://mclo.gs/kn5Qkk2 debug.log: https://mclo.gs/zIKoAaB crash report: https://mclo.gs/j86C10Y The part of debug.log that I think is the crash (after Create mod already loaded incorrectly): [02May2025 14:52:36.813] [Worker-ResourceReload-2/ERROR] [net.minecraftforge.fml.javafmlmod.FMLModContainer/]: Exception caught during firing event: com/simibubi/create/content/redstone/displayLink/DisplayBehaviour Index: 3 Listeners: 0: NORMAL 1: net.minecraftforge.eventbus.EventBus$$Lambda$1770/0x00000008009bc8a0@70223c71 2: ASM: class com.momosoftworks.coldsweat.core.event.PotionRecipes register(Lnet/minecraftforge/fml/event/lifecycle/FMLCommonSetupEvent;)V 3: ASM: class com.momosoftworks.coldsweat.compat.CompatManager$ModEvents setupModEvents(Lnet/minecraftforge/fml/event/lifecycle/FMLCommonSetupEvent;)V java.lang.NoClassDefFoundError: com/simibubi/create/content/redstone/displayLink/DisplayBehaviour at TRANSFORMER/[email protected]/com.momosoftworks.coldsweat.compat.CompatManager$ModEvents.setupModEvents(CompatManager.java:501) at TRANSFORMER/[email protected]/com.momosoftworks.coldsweat.compat.__ModEvents_setupModEvents_FMLCommonSetupEvent.invoke(.dynamic) at MC-BOOTSTRAP/net.minecraftforge.eventbus/net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:73) at MC-BOOTSTRAP/net.minecraftforge.eventbus/net.minecraftforge.eventbus.EventBus.post(EventBus.java:315) at MC-BOOTSTRAP/net.minecraftforge.eventbus/net.minecraftforge.eventbus.EventBus.post(EventBus.java:296) at LAYER PLUGIN/[email protected]/net.minecraftforge.fml.javafmlmod.FMLModContainer.acceptEvent(FMLModContainer.java:121) at LAYER PLUGIN/[email protected]/net.minecraftforge.fml.ModContainer.lambda$buildTransitionHandler$5(ModContainer.java:127) at java.base/java.util.concurrent.CompletableFuture$AsyncRun.run(CompletableFuture.java:1804) at java.base/java.util.concurrent.CompletableFuture$AsyncRun.exec(CompletableFuture.java:1796) at java.base/java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:373) at java.base/java.util.concurrent.ForkJoinPool$WorkQueue.topLevelExec(ForkJoinPool.java:1182) at java.base/java.util.concurrent.ForkJoinPool.scan(ForkJoinPool.java:1655) at java.base/java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1622) at java.base/java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:165) Caused by: java.lang.ClassNotFoundException: com.simibubi.create.content.redstone.displayLink.DisplayBehaviour at cpw.mods.securejarhandler/cpw.mods.cl.ModuleClassLoader.loadClass(ModuleClassLoader.java:141) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:525) ... 14 more [02May2025 14:52:36.972] [Worker-ResourceReload-2/ERROR] [net.minecraftforge.fml.javafmlmod.FMLModContainer/LOADING]: Caught exception during event FMLCommonSetupEvent dispatch for modid cold_sweat java.lang.NoClassDefFoundError: com/simibubi/create/content/redstone/displayLink/DisplayBehaviour at com.momosoftworks.coldsweat.compat.CompatManager$ModEvents.setupModEvents(CompatManager.java:501) ~[ColdSweat-2.3.12.jar%23537!/:2.3.12] at com.momosoftworks.coldsweat.compat.__ModEvents_setupModEvents_FMLCommonSetupEvent.invoke(.dynamic) ~[ColdSweat-2.3.12.jar%23537!/:2.3.12] at net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:73) ~[eventbus-6.0.5.jar%2387!/:?] at net.minecraftforge.eventbus.EventBus.post(EventBus.java:315) ~[eventbus-6.0.5.jar%2387!/:?] at net.minecraftforge.eventbus.EventBus.post(EventBus.java:296) ~[eventbus-6.0.5.jar%2387!/:?] at net.minecraftforge.fml.javafmlmod.FMLModContainer.acceptEvent(FMLModContainer.java:121) ~[javafmllanguage-1.20.1-47.4.0.jar%23784!/:?] at net.minecraftforge.fml.ModContainer.lambda$buildTransitionHandler$5(ModContainer.java:127) ~[fmlcore-1.20.1-47.4.0.jar%23783!/:?] at java.util.concurrent.CompletableFuture$AsyncRun.run(CompletableFuture.java:1804) ~[?:?] at java.util.concurrent.CompletableFuture$AsyncRun.exec(CompletableFuture.java:1796) ~[?:?] at java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:373) ~[?:?] at java.util.concurrent.ForkJoinPool$WorkQueue.topLevelExec(ForkJoinPool.java:1182) ~[?:?] at java.util.concurrent.ForkJoinPool.scan(ForkJoinPool.java:1655) ~[?:?] at java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1622) ~[?:?] at java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:165) ~[?:?] Caused by: java.lang.ClassNotFoundException: com.simibubi.create.content.redstone.displayLink.DisplayBehaviour at cpw.mods.cl.ModuleClassLoader.loadClass(ModuleClassLoader.java:141) ~[securejarhandler-2.1.10.jar:?] at java.lang.ClassLoader.loadClass(ClassLoader.java:525) ~[?:?] ... 14 more
