So far with the current patch the only things I've noticed (I haven't really been one to play betas before now) is that sometimes I get a graphical issue where when I'm in the campaign map I'll get this flashing effect.
dunno from your description if its the same i had
but
enabeling V-Sync fixed my problem that looks very similar
Edit:
about wars:
yes i noticed this too
iE: Rhageha(sp) had 2 wars in which she did ok but in no way good and she decleared war on the largest power ..
and what i noticed
she gave me nearly every effing castle ot town she conquered
i did hold Razih and Hubyar and 4 castles around there and
she gave me Sanopea and Lageta
edit 2 i was married with Ira maybe that was part of her favoring me =)
but i doubt that
