Planet flipping, or lack of...
Hi, I am playing the original game fully patched, largest map, 9 ai, "tough" difficulty. I currently control over a third of the map and have an influence rating through the roof. My current problem is that I have several (read:around 20) planets in my borders that belong to the ai and are marked red, having a foreign influance rating of over 4.00. Some of them have over ten, one even 19, and yet they dont flip. Turn after turn, some of them have been red for years and years, and yet they still hold on. Is there something im overlooking or doing wrong? Thanks!
