So I want 2 mod setups, 1 for co-op and 1 for single-player. I'm assuming there's a file somewhere that tells the launcher/game which mods to load when I click play.
What is this file and where is it stored please? So I can just switch 2 copies of this file in and out, rather than disable/enable 30+ mods everytime.

Thank you.

P.S: Can't use Kaedrins mod manager as it breaks multiplayer for me[link].
