Yes I would like to point out a ery good leason I learned from this issue. When you get a corefile, READ THE STUPID THING. My problem lied in mob_hit yes but not at the first time it called melee_hand_to_hand but at the bottom the second time it called it down where if the mob is an area_attack_mob. Now had I read the corefile and went to the line number it hand told me. I would have found this issue much quicker. So it is always wise to fully read something rathern then to quickly skim it :P
