This mod currently has a bug: when you selecting any option that isn't Cetana it will set a flag to prevent Cetana from spawning, but this same flag is used to make FEs go into panic mode. This panic mode blocks you from declaring rivalry, declaring war, making claims, trading, or insulting them.

Interestingly this particular bug isn't the fault of my mod. After Cetana happens naturally the flag is set. After Cetana is defeated it is never un-set, because then she could spawn a second time. This means that any Comogenesis-spawned FEs will immediately enter into a state of panic, and can never have wars declared against them.

The only current options I have are to mod the crisis_selection event – but doing so will mean this mod never works with any modded crisis that gets added to this event, or to mod the five diplomatic actions which check the flag – which is guaranteed to break any diplomacy mods which touch those actions.
