I was in PVP and for some reason when i chose moves it wouldn't do anything. I couldn't walk, attack, heal or anything! Plus now my friend thinks she is better because she took that as advantage and healed then attacked a lot. By the time it let me attack again, i was already about to die. I think I remember at level 25 on my buccaneer it happened too.
