There is no script anymore, by which I mean there is one that does 1 run but every running of this script is triggered by me manually. It never prevented anyone from getting colonists either, especially since I had changed to only run it after colonists went up to like 500, so people could get them before me. And now that I do it manually, it should be similar or better.
That being said I do think there are not enough colonists on terra for the number of turns and players we have. No idea if it would still result in someone getting the lion share of them though...
