People that don't show their code, will usually just be ignored. And so will just posting snippets out of context unless the problem is obvious from the little code you post. Did you even read the link I posted about the important of the entity's controlling passenger and how it affects where to run your logic? If you did, why do you not show your RocketEntity so we can confirm you did it correctly?

Check you have the latest version the contact the mod author. My guess is their mixin is getting called earlier than they expect because of what other mods are doing?

One of your mods has failed to register an entity properly. "minecraft:pig" is minecraft's way of saying not found/registered. The logs/debug.log might have more information. But usually because it is not registered we have no modid to say which mod is causing it. Otherwise, you will have to experiment with removing mods until you find which one is causing the problem. Backup your worlds before removing mods. As a first guess, I would try those mods that have a dependency on geckolib. Generally people that use that mod, write mods from tutorials without fully understanding what they are doing. 🙂

https://forge.gemwire.uk/wiki/Registration You don't have to use DeferredRegister. You can use RegisterEvent instead. But DeferredRegister is recommended as less error prone. As to the difference. Fabric unfreezes the registries throughout the mod loading process. That makes it simpler and gives you more flexibility, but it is inherently unsafe and can lead to bugs if you don't know what you are doing. Forge only lets you register things when it is safe to do so. Forge has a state model that defines when things should be done, see its ModLoadingStages. e.g. with forge it is guaranteed that all custom registries including those created by other mods exist before any mods start registering objects. The use of the well defined state model, allows forge to run certain parts of the mod loading in parallel (in principle speeding it up).

That still shows optifine as the last line in the log. As I said above, try without optifine. If you are still getting the crash then post the launcher_log.txt Otherwise you need to talk to the optifine mod authors.

The last thing in that log is optifine. You definitely have the wrong version for your version of forge. Use the latest preview release or try without it.

Use java 17, mixin does not support java 20

Issue with valhelsia_core. Others have said it is not compatible with optifine.

Check you have the latest version then contact the mod author.

If you don't upload your logs/debug.log and/or crash report to a file sharing site and share the link we can't help you. That truncated error message you posted contains no useful information other than the game crashed.

Something is "looping", causing a stack overflow. Unfortunately, we can't see what is causing it because you hit the default maximum of 1024 lines in a stacktrace. Try adding the following to your user_jvm_args.txt -XX:MaxJavaStackTraceDepth=10000 Hopefully 10,000 lines is enough to see the cause. 🙂

Check you have the latest versions then contact the mod author.

Check you have the latest version then contact the mod author. This is going on too long. The purpose of this forum is to help people with real problems. It is not here so you can dump a large number of random mods in your mod folder and then proxy the work of debugging/fixing it to us. Build your modpack by adding individual or small groups of mods and testing it. That way you will know which mods are causing the problem. If you are not prepared or capable of doing that, use a modpack built by somebody else.

Check you have the latest version then contact the mod author.

This is a 1.16.5 support request, which is not supported here: https://forums.minecraftforge.net/topic/91712-supported-version-directory/ The ip address is for a local subnet (192.168.*.*) so it is unusable by others not on the same local network.

Check you have the latest version then contact the mod author. And you also have some issue with immersive portals conflicting with a network mixin. That is breaking other mods.

One of your mods is not for 1.19.4 so it can't find a class that no longer exists in 1.19.4 The crash report does not say which mod is causing the problem. Guess: Somebody recently reported a similar error with cgm which doesn't yet have a 1.19.4 release: https://www.curseforge.com/minecraft/mc-mods/mrcrayfishs-gun-mod/files

Duplicate post, answered on the other one.

You removed ae2 (applied energistics) which is part of the world gen for that save. Minecraft won't let you load the world without it. Options: * Start a new world * Reinstall ae2 so you can play that save * Use an NBT editor to modify your level.dat and remove the ae2 dimension from the save (backup your world/save before messing around with NBT in case you do it wrong)

Check you have the latest version then contact the mod author. It could also be you have the wrong version of create? In general, if you know which mod is causing the problem you should talk to the mod author. These are the forge support forums. There is nothing we can do to fix other people's mods.

No logs/debug.log means we can't see the error(s) and so can't help you.

Issue with Integrated Dynamics/Cyclops core. But it could also be caused by one of the other mods (underlined above) that has a mixin in this area. Check you have the latest versions then contact the mod authors.
