Randomly teleported enemy vanishes, game stuck

I was doing the level 16 treasure hunt against wyvrens, and used Whirlwind Enemies. However, one of the enemies didn't reappear, and on the next turn when Gary used a scuttle card, the game got stuck (Gary didn't do anything, can't continue).

Here's the relevant bits from the game log (full log attached):

 

Already posted not for that map or after patch tho but just saying there is another thread you should post it in so we collect the data better

 

Sad panda. Happened today. The screen is from the moment it happened so you can see why 9,3 failed. The game locked up on his next turn.

A day without smashing gnomes is just not a good day.

 

I've only ever read of problems with this spell. Does it ever work properly?

 

Never had a problem in pvp so far and the whirlwind problems seam to be map or creaturetype based since on some maps it always bugs and on others it works most of the time or possibly always.
