It seems to me the options are two:

1) Go back to turn 16 or even 15 to get Caelum and Pythium back in. Major disadvantage: You'll all have to replay 3 or 4 turns, which is really not ideal because obviously people will have learnt things by experiencing wars the first time round.

2) Deal with having only a few human players (5), I'll move you back to turn 19, and carry on as if nothing had happened.

I can't help but feel (2) might be the wiser option, but will do whatever you think best.
