Hi, campaign 20309 has a glitch appears to have 6/6 players but has not started possible because it only shows 4/6 joined?

There are a few competing systems at work here, it's been weird like this for years now.

I'll drop out and rejoin, that seems to jog it into action sometimes. It will begin, I hope! If not, be ready to join the next one quickly so we can get a six player game going.

Remember the 20 player games on the Dragon Lakes Map?
