Playing a gigantic map last night, I noticed that my planets were not increasing their PQ when I added Soil Enhancement. I had noticed this in the beta but this is the first time I have seen it in 1.x.
After I researched Ethics and chose Neutral, the planets went nuts with PQ. Some of the 6-7 planets were shown as PQ 18-22 but with only 14-15 squares of terrain.
Later I noticed that some of the planets seem to be capped at 5 billion pop, in spite of being rated PQ 19-20 with plenty of food. The mouse over confirms that it is a high Q planet.
None of rthis spoils the game for me and if it does not get fixed that's fine but since it is kind of goofy you probably want to fix it.
I can send the game file if you wish
