Thanks for replies. Seems like I messed up religion stuff in my game, unfortunately the mod is not very forgiving of these mistakes, so I have to deal with every village and town in the game hating me except for pagan ones (and no, doing stuff FOR christianity does not increase village/town relations. )
However now it happened again, and this time there was no such event. Gwent is suddenly at war with me and the bastards plundered my village for no reason.
I have managed to make peace with most of the kingdoms by using the teleport cheat (I hate doing it, but the map is just too huge), but still at war with 3 irish ones and Gwent.
Aspirine that didn't work for me, only before I had a kingdom. I asked the king of Gwent for peace, and he sees no reason to.
BTW my right to rule is now 104, which I thought was way sufficient, but guess not.
Now I'm trying to attack the irish Mumain, I have sieged and taken a castle. It seems the easiest way to do so is to prepare ladders and then try to bully a small garrison. I also tried sieging his capitol after smacking most of the field armies, but he probably have too many men (about 350+ small lords), while I have about 450 men. The problem when I try to build crenelations is that they constantly attack and burn them, making me have to start over (120 hours is just too long time).
What is the fastest and less painful way to take a city? Do you need a marshall and 1000-2000 men or is it possible to take one just like it was in vanilla? The army sizes are just sooo huge in this mod.
