Seriously, I'm either blind or plum stupid. I've read, I've googled and I know that the guide is somewhere on the wiki but I swear I cannot find it and I need some clarification on this, as my fiance and I have already had one mess up that I was able to, luckily, reverse. Overwrite mod. We have the esm files for update, dawnguard, hearthfires and dragonborn along with a back up folder from xEdit containing the back ups for those files in overwrite. From what I understand from googling (again, I can't find the blasted wiki page specifically detailing what we're supposed to do with these files in particular ;-; or maybe I have and I just can't find the answer on the page because I'm blind and stupid?) I'm supposed to delete/remove the back-up folder and place the now-clean esm's back into Skyrim/Data? Is that correct? I don't want to blindly trust stuff I'm reading on sub-reddits, claiming they're following the STEP wiki, but aren't linking back (like I keep hoping).
