Jacob Hauken, Inspector undo ability causes game to freeze/become unable to progress
Activate Jacob Hauken's ability, exile card, then game ask you if you want to pay 4uu to transform the card. Then I pressed undo because clicked on wrong card. After that the yes or no buttons have disappeared and i could not do nothing. Please return my expenses.
I also got this in a match where I probably would have got a 3-0 match score.
