Hey guys, I just wanted to give everyone a heads up. It seems in fallout 4 bodies disappear pretty quick. I was almost full weight wise and loaded up Dogmeat as well and but decided to go in and clear out the Corvega Auto Plant and then I could come back and loot all the bodies. Well just got back to Corvega and quite a few of the bodies are missing including all that hard earned loot.
So i'd suggest maybe looting all the bodies and then storing the stuff in a container and then come back and clear out the container.
Hope this helps!
