Is there an update on this issue? I seem to be having a similar problem.
My data paths are correct. After having a corruption problem, I reloaded the engine and game to start fresh, copying the mod I have been working on in from a backup. Everything seems to be fine after deleting the corrupted lsb from one level except the terrains are uneditable on all levels. I was going to bite the bullet and recreate them all but after reading this I worry it would just happen again.
