there are a few squared puzzles that have multiple right answers in the novice section however only the one you guys have for the answer will show a complete.
I loved being killed by headless archers.... and watching them shoot... after i loped their heads off... and there's glitch for the second boss if you don't kill him you won't get 170 kills so don't die
They don't have multiple answers. It's a bug in the way hints are faded. It will be corrected soon.
