Mate + Henchmonster + Illusion = confusion!

[MunchkinMan]

I'm fairly certain we covered this earlier, or at least in similar situations, and the Mate always keeps duplicating the other Monster, since that's the least amount of book keeping. So, if the player took the Mate, then the Mate becomes the same as the other Monster once it's hit with Illusion. It's dangerous to not take the Mate, because then if someone played Illusion on that, then it definitely becomes a different Monster.

And, I'm stating this as official, not just an opinion.
