So I recently started a new playthrough of Skyrim when I went to Winterhold. I had a mod that expanded Winterhold to make it bigger, but still keep it in ruins. I decided that I didn't like the mod, so I downloaded another, deleted the first from my Skyrim folder, and played. However, the first mod was still being used when I got to Winterhold, while also using the second mod I downloaded. When I checked the data folder I found the file i had deleted was back in it. This time, I deleted it again, and emptied my recycle can as well. I booted up Skyrim, went to Winterhold, and the first mod was still in use. I went back to the data folder, and sure enough, the file was still there. I have no clue why this is happening. I've checked both the files I've downloaded from both the nexus and steam, and nothing is showing the mod I had previously downloaded. I can't remember the name of the mod, and the only name in the data folder is "winterhold.exe", without quotes. What's part of the town are a couple of map markers with these areas: Winterhold: Old town, which is just some extra buildings; Winterhold Docks, and Old Ruins, some more ruins down near the shore. Again, i have found nothing in my downloaded files here on the nexus, and can't get rid of the file no matter what I do.
If somebody could at least give me the name of the mod I supposedly have, that would be great.
