Whenever I try to run certain challenge maps and all custom maps on Overgrowth, my whole computer freezes up, and I have to force it to shut down. In the terminal, it says it gets to "Loading dialogue poses file," and then everything freezes. However, other maps seem to find it just fine, and load up the desired level. Any fix?
