Wow thanks so much for the info! I'll keep that in mind if it happens to anyone else. I'm glad you found a workaround!
Someone was able to build the game for Linux -- they had some graphical problems, but I'm actually not 100% sure if it's a linux thing or a Radeon graphics card thing. A few other windows users have reported the same bug. It would be cool to have a native linux version of the game!
