Freeze: clues can't find a white spot

I've had a freeze occur cause of clues.

The reason I think it froze is that there was only one white gem available to become a clue and the spell I did cast would generate 2 clues.
It was gone missing while I had a trail of evidence in play.

All other white gems were already either supports or clues.
So the game could not find a spot for the clues and entered an infinite loop.

Probably that was the cause.
Anyways hope you fix it since Jace unraveler can easily incur in this bug.
