Well, the original fix I found involved tracking down a particular file, deleting the information in it, and then copy/pasting a block of information into it from another file in a completely different folder and bam. Everything worked.

Didn't need to fiddle with any sort of script at all. Screw scripts. Once I did this I never had a tile-related editor problem again when working with GK maps outside and in. It even correctly identified the correct indoor tilesets for different kingdoms.
