8.1.0r65103, Steam + wireless XBox controller, MAISIE_SKWE; softlock on this screen during today’s Faction Assault:
Can select the rewards and the Continue button with controller or mouse; controller A button or mouse click on a reward shows the reward’s tooltip; controller A button or mouse click on Continue does not work, remains on this screen forever. I had to force-quit the game from Steam.
The victory was counted; on re-entering the faction assault after restarting the room is shown as complete and I was able to finish the run.
