This was why I avoided energy weapons in FO3 and NV, this was why I avoided magic that could melt/burn enemies to ash in Skyrim, and it's also why I now have to avoid these weapon types again in FO4... This bug has been around for so long, but they still haven't fixed it... It's so fun having 5 or 6 glowing red ash piles at my door step of each settlement that will never despawn... Or that one goo pile in my bedroom from that ghoul attack on Spectacle island... Anyone have any idea if they ever plan to fix the ash and goo not cleaning up properly? I remember them mentioning it in Skyrim, but never fixed it, and that was 5 years ago...
