OMG!!! You're doing everything wrong at all!
Use the command /locatebiome abundance:lavender_forest and as soon as you appear, turn off the server via /stop, then go and check the crash chunks, sometimes it does not work from 1 time, you need to look for new pieces of the world and biomes from mods.
You need to turn off the server with the /stop command as soon as you find yourself in a new biome. And then start the server and fly through it again, this works in unloaded chunks
the configuration files were generated from scratch, I deleted them and tested them with new ones, without any changes. Forge: 1.16.5 - 36.2.2 and tested on other older versions - the problem remained.
At the 1st launch, there is no such biome crash, only after the 2nd launch it starts, this feeling in the unloaded area does not change, I'm tired.. I have been suffering for the 2nd month. My players have already experienced 30+ deletions of the world and the game anew because of this nonsense. Please help me.
Please hear me, I used only mods from Abnormal sTeam and AuroraTeam, I didn't use anything else, pure Forge = crash chunks are there! In solitary - everything is fine, in the north = full ass!
This mod pack is minimal, the error goes to Abnormals team and team Aurora if they are together, it is the generation of the world (biomes) it is broken there, although the developers indicate that they cannot reproduce this error.. Maybe they are stupid and don't understand me how to do it.
