i've seen a lot of previous issues about this and none of the fixes worked, i'm using a 1.16.5 modpack and as with most other issues it mentions something about botania, it seems to happen whenever i place down an autosieve and leave the game, the first few times it's fine but then the world just stops working after loading reaches 100 percent.

i lost two worlds to this
