Dear all,
The first time this happens to me:
http://www.youplay.it/play/bm_GameMove.asp?GameID=303346In turn 11, I got both a smoke and a fire chits.
Turn 13, fire is extinguished, but I still have the smoke. Turn 15, smoke turns into fire.
Is this just bad luck, or in the rules (I could not find this particular case), or an implementation glitch?
Thanks for your comments

It is both consistent with the rules, and bad luck.
