For some reason various old mods are still showing up in the CK2 launcher (and it's not just cosmetic, the game loads with them selected) despite the mods no longer existing in the documents/paradox interactive/ck2/mod folder. I've deleted the entire mod folder, verified the game's integrity, reinstalled the game, and the mods are still in the launcher. This includes mods not on the Steam workshop, and the workshop does not re-download any mods anyway (nor is the mod folder reappearing). In essence, I'm stuck with old mods that just won't go away.
