Alright, thanks Guess I'll just have to wait, then

I got it from CurseForge. As for 'fabric'. I have no idea

I only have WorldEdit installed

Updated to Forge 28.0.18 and I still have the same problem The game crashed whilst exception in server tick loop Error: java.lang.NoClassDefFoundError: net/minecraft/world/ServerWorld Crash report: ---- Minecraft Crash Report ---- // Uh... Did I do that?

I've updated to the latest version of Forge but every time I try to open a world the game crashes immediately with the error: The game crashed whilst exception in server tick loop Error: java.lang.NoClassDefFoundError: net/minecraft/world/ServerWorld This is the crash report: ---- Minecraft Crash Report ---- // Why is it breaking Time: 25/07/19 12:54 Description: Exception in server tick loop java.lang.NoClassDefFoundError: net/minecraft/world/ServerWorld at com.sk89q.worldedit.forge.ForgeWorldEdit.setupPlatform(ForgeWorldEdit.java:133) ~[?:?] {} at com.sk89q.worldedit.forge.ForgeWorldEdit.serverStarted(ForgeWorldEdit.java:192) ~[?:?] {} at net.minecraftforge.eventbus.ASMEventHandler_3_ForgeWorldEdit_serverStarted_FMLServerStartedEvent.invoke(.dynamic) ~[?:?] {} at net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:80) ~[eventbus-0.10.3-milestone.0.1+1a5fa31-service.jar:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:258) ~[eventbus-0.10.3-milestone.0.1+1a5fa31-service.jar:?] {} at net.minecraftforge.fml.server.ServerLifecycleHooks.handleServerStarted(ServerLifecycleHooks.java:81) ~[?:?] {} at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:598) [?:?] {pl:accesstransformer:B} at java.lang.Thread.run(Thread.java:745) [?:1.8.0_51] {} Caused by: java.lang.ClassNotFoundException: net.minecraft.world.ServerWorld at java.lang.ClassLoader.findClass(ClassLoader.java:530) ~[?:1.8.0_51] {} at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[?:1.8.0_51] {} at cpw.mods.modlauncher.TransformingClassLoader.loadClass(TransformingClassLoader.java:102) ~[modlauncher-3.0.2.jar:?] {} at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[?:1.8.0_51] {} ... 8 more A detailed walkthrough of the error, its code path and all known details is as follows: --------------------------------------------------------------------------------------- -- System Details -- Details: Minecraft Version: 1.14.4 Minecraft Version ID: 1.14.4 Operating System: Windows 10 (amd64) version 10.0 Java Version: 1.8.0_51, Oracle Corporation Java VM Version: Java HotSpot(TM) 64-Bit Server VM (mixed mode), Oracle Corporation Memory: 941024568 bytes (897 MB) / 2147483648 bytes (2048 MB) up to 2147483648 bytes (2048 MB) CPUs: 12 JVM Flags: 9 total; -XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump -Xss1M -Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M FML: New FML!
