The planetary moral project does not appear to be working. I had a planet with low approval and selected the M project, it showed up as a +4 in my tool tip but approval level did not change, even waited a turn and it still did not change. I reloaded and researched Supportive Pop (same +4 as the M project) and it took effect right away increasing my approval level as advertised on the same planet where the M project did nothing.
Do not think this is new to 1.6
