Although it's too early to report and re-open then ticket but Muris's gate still cause my client to froze/hang. Waiting to test on other PC than mine to see if it's not because of my PC. Something related to WinXP or my NVIDIA 240 GT? I know one game hates my GPU, Neverwinter Nights 2 but it really wreck havoc no matter where you're in game unlike ROSE where only the gate is the problem.
Moral: Don't effing reset your unique skills after you manage to roam inside Muris City.
Just curious, but when you reset your unique skills did you lose your fate? I did and I had to go back to the temple and swear allegance to the fate I had chosen before, I was unable to finish the Orlo quest until I had my fate, so you might want to check that out. If your fate is missing, maybe it is triggering the gate issue. Just a thought.
