Game Mechanics: Auto-attack issue

[Mordachai]

happened to me several more times tonight in crushbone. not frequent enough to cause deaths or what have you, but i'd say at least 10 times.

[Zanti]

Happened to me in various places also.

happened here aswell: no autoattack but specials (backstab) worked. no oor message either. if i moved from behind to the side of the mob and turned a little, autoattack resumed.

I was getting all of yesterday and this morning on my rogue in Solb. All i could do is backstab. luckily the mobs would die fast
