I'm MP4, and when I have 0 heat, everything runs fine, but the second I get heat, the game slows down proportionally to the amount of heat I have. 2000 heat makes it go slow, and 4000 makes it take about 30 seconds just to register I clicked something. I also almost have too much loyalty, so i can't donate it. The only thing I can do is wait for the heat to go away, which takes way too long.
