I'm having an issue downloading TCTS, i tried putting the .esp file in my mod folder through vortex and it wasnt loaded into the game, and when i launched the game it was as if nothing changed. same with if i put the entire .zip file. How can i fix this?
Not sure. That doesn't tell me much. Make sure the .esp is ticked in your mod manager, it sounds like it's not enabling for some reason. And you have the NVSE plugins.
I strongly recommended everyone uses the Faction Compatibility Fix file too. It will help with edge cases based on your particular load order.
