To clarify, a monster moving into -you- can give you the back attack (as in you get the free round, not them). I can't seem to reproduce it beyond having one person in my party to stand behind me, and waiting for the monster to approach me while I face north.

I've had it happen while facing other directions, so, I'm not entirely sure which parts of the monster/player are causing that to happen.

I'd imagine this fix should stop that from happening, though.
