i dont really have any words for this, but the hydra lair is completely broken/missing in some areas. and in other areas, its misleved.

I’ve seen this about 4 times in development and it’s looked perfectly fine. You’ll need to give me seed and coordinates

I figured out the cause of the problem anyway, no need to

i have no idea where those coords are. i traveled like 20,000 blocks or so in that world

alright, thanks for taking care of this
