I just recently unlocked custom scenarios and I created a World War Two template. However, when I created the game no one could see the "Message from Host" which contained the rules for the game. I assumed your supposed to put the rules in the template description but I was apparently wrong. Where exactly am I supposed to put it so everyone can see it?

It looks like you set the description for the template instead of the message from host. If you want to modify things, modify the template (start the game creation process but go back and customize the settings), put the message from host where you would put it if you were just creating a normal game, and then save the template once you're done changing the settings.

Or was it a bug? If so, could you link to the game? In both Flash and Unity, the message should be visible in both the lobby and game settings.
