Losing one player, potentially two, is not good that's for sure. Don't think I'd say it's collapsing yet, but certainly some deterioration going on.
I've PM-ed tgbob to see if a longer hosting schedule would help keep him around. And I'll see what I can do about helping in the search for a Pangaea sub. It would be very sad for a nation that has endured as much a Pangaea has, and survived, to have it's ultimate fate sealed by the AI
Thr current turn may be getting delayed if it helps in keeping both Caelum and Pangaea under human control.
Keep you all (or whoever's left) posted.
