So my question is: is there any way to fix this? I'm really proud of this dungeon that I made, but if I release the mod as is, it will screw up so many other cells. Am I screwed? do I have to remake the whole dungeon in a new plugin file?
I did check, loading up the Skyrim.esm file without loading up the messed up .esp file fixes the problem, and the object is present in cells.
Would re-downloading Skyrim or the Creation Kit help?
