what's the weirdest way you crashed the game? mine would be: spawning up 9-11 cars on east coast usa then putting them on AI mode random, putting 0 gravity on, waiting 2 hours, then watch one of the cars hit the water. I just noticed that I put 9-11, that could mean many things.....
I tried to mod a covet to have two engines. it came up with "fatal vehicle exception" (like with outdated mods) when I reloaded it, the game crashed.
I crashed the game hard today because I set the spring value for my spinner too high, Ctrl-R twice, then the game froze.
