It did uninstalled and reinstalled all my mods (147 at last count). Problem is it only did it on paper, so to speak. More than three quarters of my mods didn't actually install or work afterwards, meaning it's in the directory but even skse and loot can't "see" them. Therefore, Skyrim refused to load. I had to manually reinstall ALL mods, sort them, clean them, fix all master/slave. everything. Manually. It was a colossal waste of time. I restored my settings and will just stick to the old version. Sorry, guys. I know you're trying but even if it reportedly "worked" for thousands, it still isn't a good version. So yeah.
