Again me
I bought the book for the dueler mission, I did not know what it was so I read it before starting said mission. Now I cannot read it again, so that bit is cut out from the questline and when I go to the Arena there are only normal fights, but no dueler fights.
Another couple of weird things: i am super powerful (in game), but the only ones who declare war to me are the weakest factions (owning only one city weak).
I am really friendly with the ROTF and Gunnar is my best buddy, yet they never accept any trade agreement or else (i send a noble with 7 or 8 persuasion).
