@DarkAmaranth1966 Thank you for the response!
I did as you suggested, the save loaded fine and saved ok, and I could reload it afterwards too. But again, as soon as I entered Cullen's office, everything broke again.
Did the registry cleaner and rebooted and repaired, still nothing.
But I think I might've found the culprit. I believe it was caused by an outfit retexture for Dorian (the all-black one), it was the last mod installed (although it worked fine for a while). I removed that mod and everything seems back to normal, no missing/uniteractable characters, and all the furniture and architecture seems back to normal. I can talk to Cullen again, and it even triggered a cutscene, so I guess that's a good sign.
I was so sure it wasn't the mod, since it worked fine for a while ☹️
I'll continue to pay attention to any other changes, but hopefully there will be no more crashes. I'll update if anything more changes.
Mods can do that. I test new mods by themselves, in a saved game I keep just to do that. If I can use it there for one hour and do everything possible then I put it in my main game, if not, I've found a faulty mod and can tell the creator what problem it caused.
If it acts up in my main game, it's a conflict with another mod and, yes outfit retextures can conflict. Sounds like Dorian's and Cullen's outfit share a texture file but, the mod only altered Dorian's outfit, the texture file was then a bad file on Cullen, thus the glitch.
