Hey,
Thanks for the reply.
Unfortunately, the patch didn't address this issue at all (it's not even in the notes). I didn't have problems with Raedric's Keep in one of my saves that made it through GV but I forgot to talk to the dwarf woman and I couldn't progress the main quest, because once I wanted to go back to GV, there was a crash.
I tried your method before, and I tried it now again, hoping - nada. Still the same.
It's actually funny - my first character got through GV and all good, I was able to kill Raedric just fine, but when I wanted to go back to GV, crashes started.
I started a new char, still the same.
I updated the game with the patch, new char, lo and behold got into GV. Talked to everyone and did everything in the main hub, went to the inn. Saved just in case, wanted to leave the in, CRASH. I was furious. Loaded the game again, tried to go out of the inn, it loaded just fine. Got into smithy, saved just in case, decided to leave, CRASH. What the... Loaded the game again, quit the smithy again and it worked. Few times like that and it was alright, decided to just endure this part with constant crashing. But now after getting into the Temple of Eothas it is impossible to load GV without a crash. And all I need is to talk to a guy in the GV hub so he will tell me to go kill Raedric :/
