Ok another bug. I have defeated my first villain in Thassilonian Sins, after which everyone at the location can move to another location. There were 3 characters at the location. I moved only 1 to another location; the other 2 characters I left in that location (there is another villain there). Now, the game is stuck. I cannot recharge my weapon (I beat it as Valeros), and every character, even the character I did not move, is asking me to "confirm my action", but there is no button to click for confirm.

 

My party is Lini, Seoni, Valeros, and Meriseil. Only 2 locations were open: Ravenous Crypts of Gluttony (where we beat the villain), and  the location with the flashing staff (can't open anything to see its name). Seoni was at the staff location. Valeros beat the villain at the Crypts. Now I am stuck.

Have you tried "Vault return trip" - go to the shop and back? Or restart the game. If that does not "fix" things, you may consider forfeiting the scenario, unfortunately. I heard that this scenario is more bugged than the others, but did not observe such bugs - probably because my heroes tend to be as well-spread as possible to temporarily close locations. And because I really don't like this scenario at Legendary so there is no incentive for me to replay it.

Thanks, I hadn't known of the Vault trip trick, I will have to try it. I did quit the game several times, to no avail.
