1) Launch Demigod and create a custom game.
2) Switch over to Impulse and locate your game in the game browser.
3) Attempt to join the game.
--> Notice that the error reads: "Your version (0.95.034) of Demigod does not match the host's version (BETA.1.00)."
I wouldn't expect this to work, but I would expect a more reasonable error message. I also suspect that this occurs when joining someone else's game?
