Hello folks,

So I'm trying out building an "economic planet" as reccomended by a few posters earlier.  But I'm having some difficulties.  The planet I chose had an Agro bonus tile, and I built a Harvester on it, raising my population cap from 8 billion to 22 billion.  Problem is, the population REFUSES to grow beyond 6.9 billion!  My approval is currently at 89 percent, which isn't perfect but it doesn't seem like it should flat out prevent birth.  I've even tried putting a recruitment center on the planet; no dice.

Anybody know whats going on here?  Is there a glass ceiling on certain qualities of planets that you can't really exceed?  Thanks again for the help.
