Firefly
This mod replaces corpse flies with light particles.
This mod does not change the sound of flies.
I use this mod with the "Flies Are Muted" mod.
Import is not required.
You can remove this mod safely whenever you need.
-Note-
The fly effect appears about 4 in-game hours after a character’s death.
Therefore you may not see many "fireflies" if you have diligent sweepers.
