I have noticed fairly recently in my travels that I have traveled back to locations where I gotten critical kill shots on enemies and turned them into piles of ashes (due to laser weaponry) or green goo (due to plasma weaponry). During one settlement attack on the Starlight Drive-In I had killed a couple of Gunners and then killed the last one near the snack counter with a critical shot from my plasma sniper rifle turning him into green goo. A few game days later I had returned to the Starlight Drive-In only to find that unsightly pool of green goo in the middle of my settlement with the rest of the gunner bodies vanished. When I go up to it it just says "Press button to activate", except that doesn't do anything. I have also come across a pile of ash while defending Hangman's Alley again that I know couldn't have been caused recently that also has that "press button to activate" thing as well. I dimly remember a similar problem from Fallout 3 but I was wondering if anybody could tell me if these will eventually disappear or if I will be stuck with these unwanted sights in the middle of my settlements forever? Any information on this puzzling matter would be greatly appreciated. As an Xbox One user I can't just use voodoo console commands to make this crap disappear.
