We go through the portal to get to the biomes/cities/islands and it crashes. For the crash log provided, it seems to be caused by rendering specific particles but I don't know how to fix that.

crash-2023-02-20_23.44.38-server.txt

edit: idk if this changes anything but the server world is a copy of a singleplayer world, the singleplayer world has all the same mods and it doesnt crash

same problem on Fabric
trying to figure out whats the exact reason
Was traveling from x 0 z barely changed and ended up at x=-2305.97, y=103.69, z=-321.36
tell me what to send so you can see where I was close too (structure/biome)
The error message refers to src/main/java/org/betterx/betterend/blocks/AncientEmeraldIceBlock.java to the method makeParticles of AncientEmeraldIceBlock.java class with a null pointer exception
crash-2023-02-23_22.44.23-server.txt
refrence to method for whoever wants to see here

Ok edit:
I just replicated the crash in the overworld
I made a 2x2x1 anciendemeraldice pool and put 1 source block on it and it crashed with same error

tried same think in singleplayer
didnt crash and I see the culprit I think freezing water making snow particles

server again

after crash joined to this

frozen water next to the emeraldice

and crashed shortly after

Hope this helps the developers
