This problem has occurred a few times now, and I'm not sure whether it's the engine or your characters, but when I kill a large amount of the mob zombies at once (like 5 in a row) FPSC crashes and I get this report:

Not sure if it's of any use, but it may be a problem with Project Blue. I'm not sure if it also crashes with other characters.
