I had the same event pop about 10 times in 15 turns for the nature league I kept saying no because I had no colonization targets but it just kept popping up. Is this suppose to happen?

Also when the AI ask me to go to war with one another there are things listed that it will do if I say yes or no like when you colonize planet or get an anomaly. Like gain items or such is just correct or just a tooltip glitch?

Lastly some improvements are show to be built on worlds that are full while others are not I’m not going to say how long that took me to figure out but is that by design?
