Thanks for the heads-up. As a work-around, try using the map to fast-travel to a new location. If you have it, that is. Prospero should give it to you automatically when you visit him on or after Day 3, I believe. If I recall correctly, the game won't let you use the map in Tyr at night (gates are barred), but if you rest until Day, it should work to get you out of there.
