I got some kind of bug on ultimate... Forget getting the flower, I didn't even get a chest. Or some of the enemies including the last boss. They were empty squares that when I passed them I went into battle mode and instantly won (yay?). And that's the only 3-star I got because RNG screwed me on all three of the other maps. Maybe there'll be a maintenance later so I wouldn't spend a lot of gems to grind the last map just yet.
