For some reason, in one round of a duel, it did not give me any indication that the other person had guessed, and so I was timed out before I could guess. In the replay it doesn't show a countdown coming up and there wasn't the audio countdown sounds either.

The countdown worked for the other rounds in that duel.

I'm sure the other player would've still beaten me overall, but I would've liked to stick my SW Wyoming guess in for that round :(
