1.2.6.4 Assaul on the pinacle: Freeze at reward select phase

Steam

v. 1.2.6.4

Story mode

Normal difficulty

Seelah, Lem, Lini and Merciel

Lem meet Most High Ceoptra at The Lengs Device location and wins (no card left in his hand) Lini recharges spell and game was stuck at confirm this action text in the screen. Most likely waiting for reward screen to chose card type.

Going to vault did freeze the program. 

When I did shut down the program and restarted it, I was able to continue from Linis spell recharge attempt and then game did go back to Lem and continued normally.
