Is it possible to create npc's within some of the settlements whose job it is to clean up dead bodies. i know "zap" is out there and if i have to i will use it. but IMHO it is not lore friendly, ist immersion breaking and it's one more thing that i dont need in my inventory. where as it wouldn't be a far car that settlement would have someone whose job it is to clean up. freeside specifically starts getting riddled with dead bodies. hell the followers of the appocalypse would have enough reason to take dead bodies to use as cadavers for teaching and training. quests could be made to collect bodies for an evil, mad scientist. honestly i just want the dead bodies gone in such a way that make practical sence. thanks for taking the time to read this.

They go away after 72 hours, most of them anyway. A couple of named ones, like Cook Cook, have permanence.

Iirc there was a mod where you can pick up bodies and bury them, Alchestbreach did a video about it but I forget which one, I'll try to find it.

Could be this one?

For myself, I'd rather have one that removes them automatically and quietly in the background. I think War Zones has a script for body cleanup. I don't remember if it worked on all dead bodies or just those it created...thought it was all, but could be wrong. I had to quit using it, because it introduced too much stutter into my game.

As to modded weapons, AWOP has it's M series of modded weapons, which while not vanilla mods, are still potent...and you can add mods to them. I just use Weapon Mod Recipes(Realistic esp), as I rarely find the weapon mods I need most, otherwise.
