I dont know it's a bug or feature but neutral empires seems refuse to reply any of my diplomatic treaty offer.
Also, the Amonkrie ask me to give them intelligence help cuz they buildings sabotaged in some way, but there was nothing any details what they want EXACTLY from me (how much intel points by the way, or how many times: only at once or for years??). I espionaged them for 3-4 turns(no sabotages), when I noticed they only contacted with me and a neutral empire, so it's possible they request help from an empire who espionaged, even sabotaged them in the previous turn?
And last: I caught my own Non-Intercourse offer when espionaged they communication channels. Weird
