Anyhow
I was messing around in the editor today when I put in an AI unit (Alien Hunter) and all the sudden it froze up and everything was... glitched out. I'd be grateful to post some screenshots but I don't know how to take them with windows 8.
Until I'm able to post screenshots here is the best description I can give:
When I hold down the right mouse button to change the camera angle, things start duplicating (for example, there is a picture of a person above an AI unit that will be --here--, and when I move my mouse downward, another one will end up ......... --here--, and so on until I stop holding the RMB). The only part of the map I can see is a tiny diagonal line going from the top left of my screen to the lower right.
--Edit--
