TileEntity

Is the log complete? Maybe also add the latest.log instead of debug.log Also make sure you removed the client-side-only mods

Add the fullcrash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

Looks like some kind of bug with this mod - try older builds: https://www.curseforge.com/minecraft/mc-mods/wyrms-of-nyrus/files/all?page=1&pageSize=20

There is an issue with overloadedarmorbar - make a test without it

Make a test with another Launcher like MultiMC or AT Launcher

Make some tests with other Quest Giver builds https://www.curseforge.com/minecraft/mc-mods/quest-giver/files/all?page=1&pageSize=20&version=1.18.2

Completely reinstall the server - also try another directory or other forge builds

I have no idea - maybe an issue with the server directory Exception in thread "main" java.io.UncheckedIOException: cpw.mods.niofs.union.UnionFileSystem$NoSuchFileException: assets

Use Java 17 instead of Java 21 Then add the new crash-report/log

Add the crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

Remove phosphor

Where did you get this mod? Looks like this mod requires another mod to work Caused by: java.lang.ClassNotFoundException: git.jbredwards.nether_api.api.structure.INetherAPIStructureEntry Nether API or similar

Same issue without Into The End - 1.1.jar?

Do you also have chunkloaders active - or forced loaded chunks via FTB Chunks?

Also add the latest.log from your logs-folder

Install Java 17 or 21

Make a test without entity_model_features and entity_texture_features

Also add the latest.log (logs-folder)

In the server.properties, set max-tick-time to -1

Make a test with an older Forge build

Delete the server.properties and test it again

Add the full latest.log (server logs-folder) with sites like https://mclo.gs/ and paste the link to it here

Make a test with another Launcher like MultiMC or AT Launcher
