1. Pirates still raid the player at the top of the list if no bounty has been placed. This is really annoying, not to mention unfair in single player games.
2. Pirates seem to take the players money without actually ever carrying out the mission. This doesn't happen all the time, but often enough to be a bug.
3. With the latest version, I've not been offered a single mission after perhaps 15 hours of play, in various games.
4. In the same 15 hours of play, I've been offered a total of 1 pact (the lowest level) despite having maxed out relation.
5. When offering pacts, AI seems to accept then instantly reject them, for no apparent reason. This results in the "pact accepted" sound playing, when it hasn't been. Also, the relation value fluctuates when this happens, and lower level pacts only get accepted when the relation values are way over the requirements, with the highest level pacts often never accepted. This suggests a bug in the relation value the AI is making decisions on?
6. The race relations modifier is BROKEN. It gives a boost to "alien" factions, so that they begin liking you more than same-race factions do. Researching the tech to "remove the negative penalty" then removes the positive boost, and your relations with alien factions drop.
7. I don't like the idea of just researching a cheap early-game tech or three to get everyone to like you more. IMHO these should be removed and the idea of tributes (give X per second of resource Y to faction Z, for a permenant relation boost of A while the tribute remains) which I've seen suggested a couple of times should replace it. This would sit nicely with the limited temporary boost from random donations that already exists.
As it stands, diplomacy (the act of, I mean) was more complex and more realistic with entrenchment. This is beta, I know, so I'm not worried yet... but if these aren't fixed before diplomacy is released, I'd probably not play it.
