Just after I went into Nipton I followed the road out of town towards Wolfhorn Ranch, when I got to the truck thats got the Sunset Sarsaparilla in (just after the railway crossing) I noticed that many of the items were half burried in the ground... what was even more spooky is that some of them slowly rose up out of the ground when I got close. But a number remained in the ground, if I pressed R3 to try and pull them out, they wouldn't budge, upon pressing it again the item dropped further, it could NOT be selected, or moved.
Fortunately these were just bog standard items that you find all over the place so I thought little of it.
Then I arrived in Novac and quit the game...
Went back onto the game and installed patch 1.01 (I still want to know what (if anything) it does)
Currently I'm near the end of "Come Fly With Me" and going back out of the rocket centre to look for the rocket parts... Just over by the waste disposal area where there should be a body which has a component on it.
I got to the waypoint and couldn't believe what I saw.
The body was half burried in the ground, you could just make out it's yellow radiation suit and the face mask. Fortunately I was on this instance able to loot the body and the key item.
However, imediately after the body shifted position, further into the ground, making it impossible to loot, or move by the R3 command.
Why yes, I do have a picture.

When you look at that picture, I could only get the option to search the body if I moved the target over the head and the knees.
After I looted te body, I tried to move it using the R3 button command... this is what happened.

When you look at that picture, despite being able to see the head and part of the torso, it cannot be selected.
And yes I did re-load to see if it would fix, and no it did not.
So if you encounter an item half burried, refrain from using the grab command or else it'll be gone forever, however, if the item is already inside out of reach, there is no way to get it out. It might be possible with an explosion, but I highly doubt it since the Havoc engine drags items down, so with no solid matter below the map floor, the body/item will always fall further down.
Again, I won't hammer home how this was also an issue with the last game. People... items... falling through the floor.
