Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

There is a door in the upper level that leads outside onto a balcony. But once there you get stuck. Apparently teleport doesn't work either.

Yep that one got me as well!!!

The door says "The way back into the castle is closed shut, however you can still access the courtyard below."

Except there is no courtyard access at all and there is some seriously glitched walkmesh on that ledge!

Sorry about this, it was supposed to give you access back down to the main courtyard. I'll get on this and send in a fix. It might be about 3 weeks until this gets fixed, so please avoid the upstairs exit in Dragonspear for now. Thanks.
