First became aware of it at the animal farm near the old nuclear test site. Half the animals were missing when I returned to the area for the second time. They re-appeared when I left the area and came back for the third time. According to the GECK, they do not re-spawn so I know they hadn't been killed.


Noticed it again when loading a save on a hill with nothing in sight. Found myself surrounded by bighorns. Right next to the bull. They weren't there when I saved.


And I've just had the same thing bite me at Scorpion Gulch while looking for a laser pistol. Cleared the area out of bark scorpions, and noticed there were no giant rad-scorpions, despite having seen some when exploring from eastern side earlier. Also couldn't find the pistol.

So I saved the game and loaded up the GECK to find where the pistol was supposed to be. Shows it sitting clearly on a rock in the middle near a dead NPC that was definitely not there in game.

Started FNV again and loaded my save (right next to the rock in question). This time the NPC is visible, the pistol is visible, and the three giant rad-scorpions surrounding me (and a fourth near-by) are very, very visible.

I've noticed this and it answers a lot of as to why things seem so empty. It really needs to be one of the top priority bug fixes.
