This is a copy of an original area
ARD008 aka (AR0508) Durlag's Tower, fire elemental challenge (fourth subterranean level) The area name depends on which game you use.
So maybe it can be repaired by making a copy of the mos from that area with the name T-1002.mos.
Yeah, thanks although I have no idea what other 3 are.
It's not possible to make that out, they're just too small and insignificant. All are copies of original game areas but their size is corrupted. One is a tomb and the others are small inside rooms. No clue.
