bug with Part 3/7 Win 1 superior potion from stage 10 or higher of Spirit Keep
I have won several superior potions but it's not completeing the Dungeon Mission. using a Galaxy Tab A7, android, google play. Sorry I'm a bit of a luddite LOL
Are you getting the Superior Spirit Potion or the Greater Spirit Potion as rewards? Check in the Tavern under the potion mixer to make sure. I've made that mistake myself.
