on the latest version:
-regurlarly getting random "Kingsmoot" popup (as Dragonlord of New Valyria or King of the Iron Throne alike) saying one of my vassals smashed his own teeth in (no effect)
-Aegon I's fertility seems rather low (checked with console, it is 20% in a default new game). In 3 out of my 4 games Orys ended up inheriting whatever titles Aegon held, since he failed to impregnate his sisters.
-Patricians of Essos declare slave raids on targets they can never reach lacking in ships/AI refuses to raise ships and ship in the army (likely vanilla ai issue, but I think there's some triggers since in some cases it works just fine, and then I see the very same Triarch declare his next raid, raise a new army and simply let them wait at the shore till it is ticked off to 100% and he loses. It might be related to them not having enough ships to embark all men, and the AI refusing to split the army in half)
-Some Lady in Dhorne at the conquest bookmark is apparently married to herself (and also managed to get five children for whom she is marked as both parents, making her parents the children's grandparents on both sides), I do not recall which fief it was but she held a High Lordship
-Grand Hunt not available for followers of the seven anymore, apparently
-Norvos and Qohor have starting trade posts located in ruined provinces, not sure if wad. Particularly useless since colonizing the ruin erases the trade post.
-lots of buggy tooltips:
on the event where you marry a lowborn woman to your son and ask for the dowry, but instead create her parents (I AM DERP AI). Btw I LOVE this idea, since this way I can make that wonderful talented girl's family nobles too (and inherit the land back once I am my current grandson and she dies!)
on various events that raise lifestyle trait counter (hedonist whenever flirting with someone else's wife, gardener after the summer fair are the ones I have seen)
likely more I forgot which are less present
-when setting Ironborn armies as looter and entering a province to raid, the hostile timer is set for 1800 days, enforcing the ai to keep their troops raised in stalwart for years after a raid is long over
