I went into the Dawnstar sanctuary to complete the mission and I noticed the following:

*whenever I would open the map-magic-skills-items menu during this dungeon, the "press A to travel to skyrim" prompt would flash.

*when I went to the door to leave, it was gone. Replaced by a darker texture of the stone walls. The travel prompt would appear, but would not do ANYTHING.

*all of my saves are in this dungeon, trapping me because I can't fast travel out.

*I am playing on an original xbox 360, and the game is not installed, my xbox is running the latest version of LIVE and not the beta of the next update.


Any fixes or confirmation that this bug is occurring in other games is appreciated

I simply re-loaded my game, and the door appeared. So just try that out if you're also having the same issue.
