Sculpting issue

Hello! I am (new new). To unreal and game creation in general and I am attempting to learn the basics. So I am attempting to make a small mound here and it looks good while molding it, but the moment I move (free cam or simulation) the small hill I have made moves, and shadows are cast. I’ve tried to smooth it, and attempting different brush strengths and whatnot, but the problem still persists.
:edit I have also tried to re build the entire lvl for the engine to crash, and i have tried to rebuild just the terrain and nothing works, rebuilding the lighting works untill the mound moves again
:edit 2 I have figured out its something to do with LOD’s but i can’t seam to find how to disable auto LOD.
