From a bug perspective: I played a Huntmaster while I had another unit on the board (Oakfather) but didn’t select a unit before my turn timed out. It ended my turn, but then the Oak Father was completly unselectable for the remainder of the game, (3+ more turns) It couldn’t more or attack. Obviously some sort of bug
From a feedback perspective: I thought I was playing an Ancient Beastmaster and accidentally played the huntmaster, I could not find any why to undo playing the huntmaster. Not wanting to pull my unit away from its Faeria collection I timed out my turn instead of moving it hoping it would let him stay. Obviously it bugged out instead. If it was possible to cancel playing a card up until you finish all the selection(s) the situation wouldn’t have happend. In the long run allowing cancellation would be the more helpful solution to this particular bug.
