I think that their problem with the clown nose quest is not seeing the dialogue options because giving the nose is not the default option. I had that problem too at first when I didn't play on fullscreen mode.
Ahh actually thought about it and realized what happened with the explosive not getting used up.
Not a bug exactly, but a strong indication that two ~similar mechanics~ need audio and/or visual cues to distinguish them if someone opens a door that they can’t see yet >.>
