Strange Game Crash

[graceful egret]

Hello!

Im playing a modpack with the fabric mod version of Terralith, and I tried to remove the mod to create a test superflat world. Strange thing is, whenever I take out terralith from my mods, my game crashes whenever I try to create/join a singleplayer world. When I put it back it works.

Anyone know why?

you cannot remove terralith from a world

Removing Worldgen Packs

There are two options for removing worldgen datapacks. One method involves resetting the dimension, while the other (Terralith only) method allows you to keep your world, but have ugly chunk borders.

Read more information and instructions on the Sawdust website!

oh wait, i misread your post, i apologize

for some reason, your game is caching terralith's information even when its removed

which should not be happening, im not sure what would be caching it

is there any way to fix it?

[viscid olive]

well, you would have to find out what's causing the caching

and what it is, im not sure. you could try to replicate the issue with just Terralith first. if it works perfectly fine with no issues, add half your mods back. repeat until you find the problem mod

Sometimes, when you are trying to figure out what mod is causing your crash, you need to result to the "remove until it stops crashing" method. Here is an efficient way to do so:

• Divide your mods in half: Half A and Half B.
• Add Half A to your game/server, and start.
• If it crashes, remove half of Half A.
• If it does not crash, add half of Half B.
• Repeat the process until it's narrowed down to the culprit!

its possible something else (incompatibility?) is causing the issue, but nothing that i can think of off the top of my head. the crash log you sent is one of "those" ones, that doesnt actually say exactly what it's complaining about (no fault of yours)
