Its weird to get the message, "You are busy doing something else and cannot hide". There's nothing else that gives a similar message, you don't get "You are busy doing something else and cannot cast that spell" or whatever. Of course once you do get this it resets the hide timer and you have to wait another 10s, then chances are you will get the busy message another couple of times. I just wish I knew what special something it is that I'm doing when trying to hide and I'd stop doing it. Its just that I have no idea, its certainly nothing out of the ordinary.
