I just got that error from the creation kit, and google has failed me miserably. For the record this error came shortly after I simply gave some default in game objects custom IDs, then on the custom ID objects I simply checked "Has distant LOD" for the custom ID objects. But this was on custom ID objects, and not vanilla objects, so I think there's a high chance it's a coincidence. This all happened in one cell by the way, with multiple errors similar to the first I posted, as in multiple objects. Is it the cell itself? What exactly happened? I'm baffled.

I'd be highly thankful for any help on this matter, as google searches have come up shockingly empty.
