...while their character just stands their looking like an idiot?
I've had this happen several times now, a few times just last night.
You're fighting and all of a sudden auto attack just decides to take a vacation, so I'm stuck there waiting for my one non-tp using skill to refresh so I can hopefully build enough tp to use a good attack while the mob is using me for a punching bag.
And I'm definitely talking about a bug, not a case of a debuff making me unable to attack. All my skill attacks work ( once I build the tp ), but auto attack does not.
Even if I push "F" to leave combat and then again to re-enter combat, the condition persist until I either kill the mob or die.
Also, it happens on random mobs, not any one in particular.
