I played the game a while, starting over a few times, then suddenly on my next restart, all the tactical mission maps go black. The only things that didn't were my lander, the ufo(if any), my team, civilians(and probably aliens, but didn't try to play it), and I think the odd car.
Looked like all this was just standing on space, with nothing else there.
I've tried multiple times to reinstall, doesn't help. I've tried searching registry for UFO and removing entries, but not much there.
Also the savegames and settings don't get removed on uninstall, and I can't find them anywhere on my harddrive, where the heck do they go?
Oh and this is with UFO:AI v2.1, windows installer download.
