Mod i never downloaded in my modfolder

[kanealpha]

This is weird: i suddenly had the mod "Active Ingredients" in my modfolder even though i never downloaded it AND another mod, AOO Zombie Resurrection inside that mod folder. I am very careful where i put my files and which mods i download so this is strange. Has anything like that happened to anyone else

They may be included in some other mod, overhaul mods for example often have additional mods included.

 

I think I even remember "Active Ingredients" as it was mentioned as part of one of the big overhaul mods.
