Yeah, but it isn't new.
And I don't actually think it's the bot. I've had this happening a lot while skinning.
Even when playing by hand, after a while you just are unable to loot mobs.
Relog, and it works again.
I've never bothered making a ticket, so I don't know if it's fixable.
Knowing Blizz, probably not!
Possibly they will just ask silly questions, which are not related to the problem.
