I oppose: That person murdered the PCs parents. Maybe the PC forgives him, but his brothers and sister? Radagos sold the kids into slavery (imagine what could have happened to the kids in that time)! It's ok not to execute him, but recruiting him would be a slap into the face of the kids.
You meade something wrong...I married Ira too, and got 5 children. And she's pregnant again. A wife who knows her duties.. But despite a relation of 46 with her mother, I got no fief until I gathered an army and seized a castle (and still needed to spend a gut sum of influence to get majority) And Rhagaea doesn't try to reunite the empire, she ends every war with western and northern traitors after a few days, just to start another war with the fleabreeding horserapers from Khuzait and Asarai. Ira is against it, but as a my wife she has to obey - I am thinking about breaking my oath to her mother.
I quoted your mistake: Don't overload your party in enemy areas. Never. It's cheaper to drop loot and prisoners than getting caught.
Good idea, but: In my case (link quoted above) the fraction leader sat in another fractions town, with an army of 1+277w that never healed, therefore he never left the town and couldn't be captured for execution. And as he was the son of the beginning NE leader, he wouldn't die that fast, besides the fact he had an army of children...
Not noticed. I will try to force it by buying workshops and doing those quests personally (usually I send companions...) in the hope some herd shall be delivered to one of the former workshop owners.
Just checked - I stopped to play that campaign on 11. Nov because of the bug and kept a save file in case someone needs it. Versions are still 1.5.3..
