i've been completing nightmare campaign with a team of 2 champs and i've successfully beaten the levels without losses however from stage 8 and up for me which were recently completed the boss levels will only give me 2 stars even though i took no losses at all i didn't even need to revive. if you complete the boss stages with only 2 champs the game will only reward you with 2 stars instead of 3 like its supposed to and its a waste of 18 energy. Please fix this asap so that i can get all the campaign rewards. the champions i'm using are tormin the cold and valkyrie both are maxed and well geared and easily clear the stages without losing hp so idk whats wrong with the game. i'm playing on pc by the way not on mobile.
