TileEntity

Backup your world and make a test without AoA3 or try other builds of this mod

Looks like the world is broken Create a backup of your world and remove it Restart the server to create a new world Then copy level.dat and level.dat_old to the broken world Delete the new world and put back the broken world and test it again

Also remove fastload

Remove chefsdelight

What exactly is the issue?

Yes If you are using Nvidia, also make sure Java is using this GPU https://windowsreport.com/minecraft-not-using-gpu/

Add crash-reports with sites like https://paste.ee/ Check for AMD/ATI GPU driver updates

Looks like some kind of issue with the loot from AoA3 - maybe a conflict with Oculus Same issue without the mod Oculus?

Add crash-reports with sites like https://paste.ee/ Remove fpsreducer and add the new crash-report

Keep on this thread:

java.lang.NoClassDefFoundError: vazkii/arl/item/BasicItem ARL is missing https://www.curseforge.com/minecraft/mc-mods/autoreglib

Does it work without Optifine?

Add the latest.log with sites like https://paste.ee/

Add crash-reports with sites like https://paste.ee/ lmft-1.0.2+1.20-forge.jar is conflicting with Connector-1.0.0-beta.15+1.20.1-full.jar - make a test without Connector-1.0.0

There is an issue with Simply-Improved-Terrain - make a test without this mod

I have no idea - maybe use a pre-configured modpack as working base and add some mods one by one

And without EpicFight?

Add the latest.log

Add crash-reports with sites like https://paste.ee/ BetterFoliage requires Forgelin - add this mod: https://legacy.curseforge.com/minecraft/mc-mods/shadowfacts-forgelin/files/2727070

There are some mods involved: Rubidium/Oculus MidnightHats/MidnightLib PlayerAnimator

Maybe the mod yuushya

Also make a test without carpeted

Are there changes without the mod Dimensional-Threading-Reforged?

Mekanism and ImmersiveEngineering In connection with Create, try Create Crafts & Additions https://www.curseforge.com/minecraft/mc-mods/createaddition

Also remove garnished, createcasing and extendedgears Maybe these are not compatible with the create build
