My fighter PC, August Breabourne was running past Aberdenn Hall inside mistlocke towards the Kobold battle today and was suddenly transported, as if passing from one area to another, outside Mistlocke, appearing as if he had left Mistlocke and entered the crossroads. No harm in it, just strange and unexpected to blip out.
These things are something that randomly, if rarely, happen in nwn. It has always been an issue that I've found to exist in the game as long as I can remember.
Just wanted to add that this has happened to me multiple times before over a more than one of my characters.
