Uh? I got a message last turn that Pangaea was permenently vanquished last turn... Do "game-over" people still need to send turns even if they have no provinces left, or does that only happen on the first "dead turn"?
On the turn that you're defeated, you actually get a turn telling you "you're defeated". You actually do have to submit that turn to acknowledge to llamaserver that yes, you're defeated.
After that, you'll be removed from the game and won't have to submit any more turns.
