It seems like after the 1.4 update bodies seem to dissappear before I can loot all of them this is the first time I noticed it. I was in quincy today farming gunners for combat armor for my settlers and after killing most of them I moved in closer to start looting the bodies and that is when I noticed some of them being gone. Their weapons where on the ground where they were at but no bodies to be found and I was using a Lazer rifle so there shouldn't of been anything to make the bodies go flying.
After clearing quincy I went over to Wilson's next door and killed a couple of super mutants on top of the building before moving in. Once I cleared the inside I moved to the roof and again there were no bodies up there just their weapons.
It seems like they lowered the amount of dead bodies laying around quite annoying I hate missing out on loot and I know I missed out on one legendary on top of Wilson's. Just wondering if anyone else has noticed this and I'm on Xbox One
