I found a structure (possibly an unfinished house?) in one of the non-safe zones right outside the starter town with a staircase going to a second floor room. Going up the stairs is fine, but when I tried to go back down to leave my character just stops moving down halfway down the stairs. I can go backwards up the stairs fine but I am effectively trapped on the second floor until I found the unstick button. Here is a picture from the first floor of the house and the stairs are right in front http://oi61.tinypic.com/2iaxzeb.jpg
apologies if there is a special way to go down a staircase in this game I have only started today.
Hi Pugo, you are doing nothing wrong, it's the owner of the house who did a design error somehow. The unstuck button is indeed there for such cases
