Yup. The relationship status is basically still not doing anything. AI's just randomly declare war all game long, even at green face with all the treaties, often asking for peace a dozen or two turns later after never sending a unit at you, because they are on the other side of the map and have no way of even getting to you.

Yeah, tributes can be cancelled at any time, which may actually be necessary of the AI isn't producing enough gildar to supply the tribute.  At least you get a fee up front so it's not a complete waste.

Come to think of it. I don't remember AI making peace with another AI player at all. Even in FA. Can't be sure, maybe it's just rare or don't receive message when they make peace. Or I just don't pay enough attention.  

Actually, no. I didn't set anything up. They offered it, then cancelled it instantly. I checked their season income, one of them was .7, the other was 2 or 3 per turn. Considering I was paying tribute early on back when I only had 3 gold coming in per season, they should have been able to afford it as well. And this isn't even an issue of wanting/needing their tribute, it is an issue of the AI seeming to have some sort of problem that needs resolution. I think. Maybe one of the folks at Stardock can replicate this issue and have Frogboy judo-chop the problem? Other than that, still no real issues so far.

(Edit)

The blood moon event.. Now that you mention it, I can't actually say. Because I do not know with whom they were familiar with at the time of the event. Like I met a faction after the event, and well because we didn't know each other during it, we were at peace. But I am fairly certain that most of the factions are at war with each other currently. They keep asking me for aid.. Gilden always seems to dominate in my games. Tarth was at the top for a long time, then Gilden overtook them and crushed them down to bottom-level.

This happens to me everygame   I call it the lunar orbit. Basically in a rotational pattern the AIs in my game meet me, setup treaties, randomly declare war, never actually fight me, sue for peace, accept peace, make treaties with me, then start declaring war on me again one by one, without me doing anything to even remotely instigate this, and it just keeps going round and round like the moon orbiting the earth until the game ends. Oh and throw in an occaisional blood moon to really spice things up. Putting up with this AI behavior all game long everygame leads to a lot of pent up aggression at the AI, I use the bloodmoon to release this aggression with reckless abandon. Smashing AI kingdoms to smoldering ruin, and when they plead for peace I tell them only their complete destruction will satisfy me ....maybe just maybe they shouldn't have declared war on me so many times?

+1 for less Flip-Floppy AI, and AI with more gumption (if your gonna declare war on somebody, you should at least try to fight them)

+1 for AI making peace with other AIs

+1 for AIs making alliances with each other(so we can have some large scale wars say Gilden, Pariden, Capitar vs Umber, Yithril, and Magnar, and so that we can see an AI attempt at a Diplomatic victory)

Frogboy says that he is going to work on having the AI ready to invade the moment it declares war.  That should help a lot.

AI doesn't have to be intelligent, it only needs to look intelligent to the player.  In FE/LH the AI seems to me to be a brainless thug, it's only purpose being, to grief the player at every opportunity. 

Just so you know, I haven't had to fight a single AI faction yet in my current game.  Been at war, yes, seen their units crawl into my territory looking for a scrap, no.  Pariden and Tarth were stomped by Gilden.  I've just been doing my Monster Hunter routine and slowly claiming rather distant tracts of land than the AI couldn't make any headway in.
