Errr wwsin got stuck

Remember the Invincible Barb bug?

This is something similar. 1 question: Did you gain a level just before it happened?

This is partly what I had explained to me, and what I've deduced:

This is a bug, has to do with using non-class skills and levelling. From what I heard, your character kind of 'resets' when you gain a level, so if you're using a non-class skill when it happens (one like WW, that lasts a bit), you are stuck in it, since the server has decided you're in default mode (while it's still waiting for your WW to complete).

To fix this, rejoin the game. On the bright side, just like the Invincible Barb Bug, you can't die in this state. I loved it when it happened, because I'd just tank the minions for everyone else to kill.
