One thing that infuriates me is when I have a battle in VATS and kill something, and it shows me clearly where the body fell, and then when I come out of VATS the body isn't anywhere near that location. What the heck?! Usually I find it way far away from where the battle took place, but sometimes I can't find it at all. It's really frustrating when you're looking forward to looting the body, but the stupid VATS seems to operate in an alternate reality.
I'm guessing others have experienced this oddity as well?
