Hallo,
it seems that the world gets corrputer and spawns weird blocks when its not supposed to like its corrupted. it also doesnt spawn in any of the modded biomes that comes with the modpack.
ive tried to see if the world gen was the issue so i tried generating in "overworld_two" and "default" to see if it that fixes the issue im having but it didnt. after that tried uploading a singleplayer world, the singeplayer world loaded everything correctly but when its loaded on the server everything goes corrupted again.
pictures attached.
First one: overworld_two
second one: default
third one: uploaded world
Server log default: Vanilla server log [#F0b2KRl] - mclo.gs
Server log uploaded world: https://mclo.gs/oj1lmS9
