I started a new game and I can't make aliens migrate to my planets. Fanatical xenophilia - there is, I am activating the decree on the planet, there is a civilization with a concluded agreement on migration, home worlds coincide, but they do not want to migrate. Previously, it worked without problems. I found a possible reason for the bug: I can conclude several contracts for migration, research, etc. at once. I conclude, the AI ​​agrees and I can conclude it again, this item does not disappear from the negotiation menu. I did not install new patches / mods, how to defeat bugs?
