Ok, here's the savegame.
Save Game, turn 136 (about 3 turns ago)
I did change the happiness.txt file to make all of them identical parms to "peaceful" and the next turn I colonized two planets (I'd just created with my Stellar Manip ships) and it made a big difference already.
Heh, I also edited the facilities, I should probably change those back, eh? ;-)
