Hi,
After the patch 29.2.2, and more precise changes to Floop’s Glorious Gloop, Boommaster Flark’s 2/6 puzzle is impossible to finish, as you only get maximum of 2 mana and can’t go to 10.
Also, that patch also broke another puzzle in Book of Mercenaries, as Snowfall Graveyard was also changed, as stated in this other thread: Book of Mercenaries Varden Impossible Onixia Puzzle
