I don't know, I go off the scene for a few days and the entire game disappears
My understanding is that the 'llamaserver disappearing game' trick is connected to the map naming somehow, and the options for fixing it are to either PM llama and wait until he can fit sorting it out into his busy schedule. Or take the initiative and just re-create the game.
I'm disappearing again now for a few days (only here now as I had to come into work for a few hours). Should be back before the weekend to resume admin duties here.
I would strongly advise against using CBM 1.7 as well. It seems to me to need a fair bit of testing due to some of the major changes it has made, and a game this size with this many players is not the place for testing, as some nations could be seriously disadvantaged due to the changes, and have their chances ruined due to no fault of the player(s). (and basic beta testing can be done in small quick throw-away games)
