So having just completed the Mages guild end quest Shalidor teleports you out of the hall.

This is where I met my first never-ending loading screen. After reloading the game I'm still in the hall and he will not teleport me again.

Trying to leave through the door gets another never-ending loading screen.

/Stuck just puts you back to the halls entrance.

And paying for a way shrine takes my gold then I get another never-ending loading screen.

I have no quest to abandon and start again because technically the quest is finished.

It appears my char is stuck here until the loading screen problems are sorted out.
