I had to reinstall Windows 10 last week. I then reinstalled ESO and Minion. I added some addons, but they were not showing up in the game. When I checked Minion, it was putting them onto OneDrive. I copied the addon folder back to the default C drive location and deleted OneDrive from my PC. That was a mistake as ESO cannot see my addons any longer. I deleted Minion and all of the addons, then reinstalled them pointing Minion to C drive again. I still am unable to get ESO to see the addon folder when I am in game.
