There are two of the three “Instance” areas in Destiny’s Reach (human starting town) that I was able to enter but was not able to exit.
These were the home area and the guard barracks that is to the right of the palace.
I am playing on Yak’s Bend server with a Norn character. Whenever approaching the entrances that I came through, I did not get prompted a message to return to the server and thus had to waypoint out. While that isn’t an enormous issue, it is slightly bothersome to have to pay a fee to get out of the area, especially considering the larger fees when you are a higher level.
