AreaCheckObject trigger (0x40D4) has been known to cause crashes.
It should return true if the given creature is determined to be in the listed area; otherwise, it should always return false (even when it just can't check the area). (I'm not sure if there were ever any steps for reliably reproducing the crashes here; it's a pretty useless trigger regardless, but it is used in some of Cernd's plot dialogue in SoA.)
