In a couple of games now I've had a bad bug where I've wrongly not been able to activate a sector on an opponent's roll. In both cases, I've had "auto-confirm if no action possible" turned on. The game flashes up "You cannot afford a card" on my opponent's turn, which indicates the game wrongly believes I should be able to buy a card, when I should instead be activating sector(s) for red rewards. In both cases, I did have red rewards that could be activated.
