Mission: Murder on the Stargazer Majestic
We just "finished" Murder on the Stargazer Majestic & encountered a game breaking bug at the end that made us unable to win:
When the murderer was revealed, I went into the engine room & completed the puzzle before killing the murderer. After that, we could not do anything other than click through the phases & wait for the airship to crash, despite having "won" by killing the bad guy & fixing the engines.
From what I have read elsewhere, if you do the puzzle first, it causes it to have the bug.
Edit: We have just beaten the murderer first & then done the puzzle with the same results.
