No it's not fixed and infact it's extremely irritating... and it sucks quite frankly there are at LEAST 3 areas you can become "Trapped" 2 of them are near the NW teleporter on the second tier... these 2 spots you can get out of with a teleport scroll or by teleporting...
The third spot that you can get trapped is in the roof over the Ankh... that rez's..... this spot there is NO way out... at all.
This needs fixed... it's needed fixing since it was released and it's still NOT fixed.
Also... there are spots where the Goblins spawn where they spawn where you can NOT reach them..... The Fairy dragons too.... this is crap... and needs fixed.
