What am I doing wrong ?

[Ars Moriendi]

Thanks for the answers. I knew I was asking the right place...

About the city stealing from under siege : it might have been the same in previous games, but I don't remember ever being so annoyed by it - probably it didn't happen very often. In this (my first) ETW campaign it happened in the 3rd siege.
Regardless of the way it used to be, it's still dumb - it would've been quite easy to make an arbitration system that looks at other factors beside "who started the battle", like : "who lays siege", "who came with more soldiers", "who killed more enemies", "who still has an army at the end". I wouldn't mind losing a city to an ally when they actually came in and turn a defeat into a victory, but to lose it to a handful of idiots who where on the field for only 3 min. before routing...
Or we could have a negotiation menu between the winning parties for dividing the spoils.
But I think I'll just follow peacemaker's advice in the future - reload and forget about it.

On the other points :
So I'm not the only one having issues with malfunctioning artillery or chasing insignificant armies around. It's strangely comforting to know there are other people having the same problems as me :)

In the original MTW, whoever got the most soldiers left at the end of the battle won the province/siege. I personally think it's a bug, one that make for a so-called better challenge.
