I got Mods for Strive: Conquest from the forum here on itch.io and unpacked them in the mod folder from Strive: Conquest, but when I open the mod section in the games main menu, there is nothing.

A successor to first Strive For Power game, currently at alpha stage · By
Notquiterandomportraits goes in mod folder. You don't need to activate it ingame tho. The folder in Tweaks are pasted into the main game folder (not the mod folder) using replace files. Lastly, paste the folders in MGEdits into the main game folder using replace files. Only the random portraits mod goes into the mod folder.
