Played a game of Battlegrounds, and had the Hero Jandice, that can swap a minion from my board to the Tarven, While nearing the end game, I swaped my biggest minion in order to incress it stats,( had the Quest when ever you buy a minion give it +1+1 for each minion you previous bought) BUT the game would not allow me to buy it back said “there is nothing thing attack”
Work without a problem up untill this point
had 3 gold, 2 board spaces open, tried to sell a minion to see if that would “undo” what ever block the purchance, and it was ONLY the minon that I swaped, that i could not buy back
Feel bad too lose the game because of that
