I am finding that some of the dungeons that previously existed are now missing walls, floors, and ceilings. I checked and it is happening our server (Rosalia) as well as on my other worlds. Basically you go underground in fly mode you find entire dungeons gone except for the lighting, traps, chests, and bones.
I tried converting one of my server worlds by moving it to the single player worlds folder. This didn't fix the issue. Is our only recourse to start a new world?
Is anyone else having this issue?
