I agree with you about the combat art, but think there might ne indexing for the overlands as they are stored with the pigpics, 2 at the end of one file and 3 at the end of the other, I think.
I may try looking into some debugging, but make no promises.
For smallpics, as best I can tell the order in the .tlbs has nothing to do with the order in FRUA, but the walls may be like this twoo for all that I know.
