Someone REALLY needs to go through these clues and make sure they are solvable. Puzzle normal 11 says Olivia and Adam made 3 exchanges only to state in a hint a little lower that Olivia made 3 exchanges, while there is not an option for 0. I encountered a couple other mistakes within the clues, but can't recite them off my head, please ensure the game is actually properly playable and solvable... For those on normal 11, Adam and Oliver should have 3 exchanges, not Adam and Olivia. Hope it helps
