The WW thing happens to me all the time in Baal Runs with my Assassin. It's like the 'Invulnerable Barb' bug, you're stuck in an endless WW until you exit the game. I think it's a result of trying to WW once or twice while still in a WW.

You can't die, but you can't do anything useful either.

The teleporting thing is kind of old news, like they said.
