Had a very frustrating moment today, was doing a Leve at Humblehearth when a Gnat hits me with a 'you can't move or take an action' ability.... which didn't go away when the timer hit zero. My buff timers also counted down to zero and didn't go away either.

I was stuck, couldn't move, couldn't fight back, couldn't heal, couldn't even quit the game. I ended up having to use alt-f4 to crash the program.
