I do not recall the specific name of the resolution, but it is the one that prevents planets from culture flipping. The issue is that planets remain immune to culture flipping even after the resolution is repealed.
I encountered the issue in 0.90, and the save game continued to exhibit that behavior in 0.95. I haven't yet started a new game in 0.95 to see if the issue still occurs in a pure-0.95 game.
