Here's some bugs I've noticed in the first few hours.

At the two table types: I forget what they're called - the one for making ammo, and the one for crafting, the ingredients on the right often start stuttering (rapidly making a sound effect) if you hover over them. There's also an annoying tendency for the ingredients list to freeze on the last craft-able item on both tables, to where it shows the same ingredients for everything you choose, and the only way to get it to stop is to exit out of the table screen and reopen it.

Mobs fall through the world and get stuck in it frequently. Many times now I've had scorpions come at me that have only their tails sticking out of the floor. This was a problem in Fallout 3 also, but not nearly as pronounced.

There's an annoying tendency for weapons to stack on top of one another in the inventory. You might have multiple weapons of a type, but there's no indication of so. This happens most with the BB guns in the beginning town. There's one propped against a house undamaged, and one in a house that has some damage. If you pick both up, the undamaged one seems to vanish from your inventory list, however the weight still counts against you. If you drop one, the other one mysteriously appears. I know this isn't something intentional, because it doesn't happen with other weapons.

PC version BTW.
