actually it was more like 1400. I cleaned them out though, and that has left my directory out of order.
Arranging by name doesn't work. The game reads them in the order they were downloaded or something.
- I since had the rather obvious idea of removing all the maps into a diff. file, starting the game, quitting, moving all the maps back in after sorting, and then starting. I haven't tried that yet, but it should work if I'm not mistaken.
