divide by zero error

[ritaxis]

I'm getting crashes with a divide by zero error. Three out of four of them occurred on a dorm lot as sims were returning to the lot in the evening. The other one occurred on a vacation lot the sim students were visiting, also when sims were returning to the lot in the evening.

The only mention of divide by zero errors I can find is in the dormbill fix thread, where it says that the fix is for a divide by zero error that occurs when there is no Myne door on the lot. But there are Myne doors on this lot, and one of the errors occurred off the lot anyway.

Any other thoughts about this kind of error?
