Yes bravo me i am going to submit a real bug report but trust me i will complain. : D
I was mining on top of a rock and i stopped mid way through to answer a question and my character froze in the rock somehow. I tried every thing to get out for example jumping, teleporting etc but it just would budge. I tried log out and exit game (which seriously got on my nerves) but it wouldn't hear of it...it just kept saying "Can not perform action while mining". Even trying to log out!!!

Suffice to say pulling the plug did the trick. It took another 15 min of trying to log back in but it seems to have fixed itself. This is not a priority bug by any means but it is worth looking in to. (seriously, i mean it, fix log in errors first) : )
