Some (possible) bugs that I have encountered:
Some scenes don't work; I've got the scene patch for 0.6 but Riverrun and Harrenhall (these are the ones I've noticed) just seem to have basic, vanilla models, especially Riverrun, which basically looks like a generic Rhodokian town. This could just be an isolated thing, though, as Moat Cailin is most certainly modelled, very nicely if I may add.
Another thing is the tournaments; they were working fine for a while, now I moving the sliders doesn't do anything except show a small error message at the corner of the screen, I'll screenshot it later for you. This means I can't change the participants or the betting.
These are the only ones I've encountered so far, though, and the removal of all the Diplomacy messages is a blessing; allowing the game to run with less interuptions.
