What irks me the most is when I get a marshalling order clear across the world from where I am.
I was playing as the Nords the other day, and had picked up some super-cheap iron in Curaw (which we had conquered). This was in peacetime, which is generally the only time I attempt long, heavy trade routes due to gimped map speed and travel time. I had just finished trading the iron for a crapload of spices and salt in Jelkala, with the intention of selling it for a mint back in the Motherland, when two things happen in rapid succession: 1) Nords declare war on Swadia, and 2) I get word that the whole gang is marshalling way the hell over on the other side of the map in Suno or someplace. Great.
Other than that...this doesn't really piss me off, but I find it weird when two pieces of dialogue from one NPC don't quite jive with one another. A couple of examples off the top of my head:
1) when I'm playing as a female, I introduce myself to the various lords of the faction I just joined, and many of them greet me with the "fair ladies bearing arms is a shame/disgrace, get back to the kitchen, make me a sammich etc." thing. Yet then they all turn around and say that they'll remain my most ardent admirer. WTF.
2) I encounter an enemy lord and he says that he heard about how I defeated Count Whatshisname, and ever since he's been eager to cross swords with me. Yet when I pick the "surrender or die" option to get on with the battle, he says something like "Oh, I had hoped we could resolve this without conflict" or "I am sad that you cannot be reasoned with". Uh, weren't YOU the one who wanted to "cross swords" with me like 2 seconds earlier?
