Hi

I have the same problem with Razor, Rayhun and Gesnizh. There is only a black screen wgile they talk and they are nowhere afterward. With Razor you are strucked in Razor's Headquater.

My bigest problem is Broken Valley after you reenter it from the Orobas Fjords.
This part has several bugs.
After I speak with Williams I get the key direkt and I don't get out. Damians henchmen only came after I reload before I enter the tower and only kill the two at the bottom after I spoke with Williams. Williams only moves when an attacker is near and return to his old position after the fight. It's not possible to speak to him again.
Like with Razor I looked in the solution to see if it is important for the main quest.
Sadly it is and the map of the solution confused me because I hadn't any Generators or Anti-Dragon -Zones. I could fly directly to Rayhun's Headquater.
The new patch hadn't solve the bugs.
What now? There is still on savegame before I enter Broken Valley but after Razor and the other Flying Fortress. I wasn't in Aleroth yet. Is that the problem? Should I try Broken Valley after I was in Aleroth? The only Flying Fortress with Anti-Dragon-Zones was Stones by the way, the first I entered.
