Game Mechanics: Random Group Bug

[Kadie]

I don't know if this is me or not... but at random intervals I get grouped bug, for 1 mob. I can't send my pet to attack and my spells don't do any damage. As well as the mob's health not updating.

I'm not lagging, as the spells appear to cast and chat goes through normally... then on the next mob it'll work fine. Never happens while soloing.
