Could you try something for me?
- Grab this special debug build of the game: http://streetsofrogue.com/sordownloadsbeta.html
- Run the game and get the bug.
- Go to the StreetsOfRogue_Data directory and send me the output_log.txt file (my email address is matt dot a dot dabrowski at gmail dot com)
This may help me find what caused the bug. I've heard of other people getting this, but was never able to reproduce it myself.
Once you do that, you can probably fix the bug yourself by following the second answer on this site: http://streetsofrogue.tumblr.com/troubleshooting
