Yeah, so I created a private dev game and invited a bunch of testers to join, but it disappeared from the My Games list, and when I checked on the link directly I get this:

Note the date created, and that it is listed as a realtime game (I definitely set the turn timer to 2 days). Not sure what's going on here, but it's wonky...
Did you make two? I'm in this one: http://www.wargear.net/games/join/517395
Yep, I made a second one after the first one mysteriously wonked out.
