I haven't really had any bugs yet. I've had one crash, and one black screen after loading which was fixed by pressing esc and then esc again to get back into the game. Nothing horrifying xD Well, random NPC faces can be horrifying. They definitely have some Bethesda Bug-Eye going on.
As a Bethesda Gamer, I expect bugs... and I expect Bethesda to do absolutely nothing about them, and I expect the community to make an Unofficial Patch. That's how things go! 😄
