If you want to spawn a large battle in prewar Sanctuary, use this file and type "bat PrewarBattle" in the console. Place PrewarBattle.txt file in your main game folder where fallout4.exe is located (not the data folder)

Cleans up dead bodies from the battle within 24 hours (leave the area and come back). Several mods on Nexus do the same thing, just a 1-line adjustment in the .esp file. Affects body cleanup time globally, not just in prewar Sanctuary.

Install like a regular mod, .esp file goes in the data folder
