Bot rebuffing

[provocating]

Just an FYI I found a strange bug. It is so strange I have no idea what would even cause this.

Create a Necromancer toon. Level him via command to around Level 20, 40 whatever...just not close to 65 as this does not work at level 65.

Now create an enchanter bot and spawn him, invite him and let him start buffing.

He will cast rune and you will never get it, he will cast until he is out of mana. I tried this on other characters like a warrior with an enchanter, or a ranger with an enchanter and it does not reproduce.

I have MGB turned on my server, not sure if that makes a difference but I really want that left on. I tried other clients just for good measure and they all do it. No idea what is different about a necromancer, so I have no clue where to even look to fix it.
