Hello, So I had a heavily modded Skyrim install (40+ mods installed) which worked fine until I tried to trial-install an ENB-modified version of Skyrim. I did so in a backup folder separate from the Steam\steamapps\common\Skyrim directory and I think I might have made some changes to the Data Files options in Skyrim's game launcher without knowing what I was doing. Afterwards, I gave up on the ENB and deleted the entire backup install from my hard disk and attempted to play the original, heavily-modded Skyrim install. When I loaded my save up, everything related to lighting, graphics and environmental textures seemed to have reverted to what they looked like in Vanilla Skyrim. Other utility-based mods and mods that add content of their own into the game, such as SkyUI, Better Sorting and various new weapons and retextures were still there, but the mods regarding everything environmental are all gone. I've tried uninstalling and reinstalling lighting and texture mods that can be easily recognised, but they did not reappear. I have reinstalled Skyrim itself, but the problem persists. I think it might be related some load order trouble, but I have no idea how to correct it without screwing up my situation even more. Please help! NB: I have tried loading up previous saves where, by the little preview image it shows, the mods are still present. The game then tells me that I am trying to load up a save with content that I no longer have. I hope this helps.
