Hello!
The above is my main problem!
1) After having installed the patch and the Expansion (now currently have v2.00.0706 PX1), I tried to travel to Caed Nua - and the game crashed. It might be that my save is full of bugs though and the problem might be aggravated because I used the console, too (just fiddling with Godmode and attributes. And I had to use teleport once because of the 2nd problem below).
2) Regions I have already visited appear as new when I go back (i.e. fog of war is there again), although my diary entries still show every quest as finished. This happened a while
