I was just about to report the same thing as I am going through the STEP process for the first time. The mod (possibly an updated version - he said he was updating some of his mods, but did not specify which) will be posted on his new profile here: https://www.nexusmods.com/skyrimspecialedition/users/93612203. Hopefully someone who has a bit more understanding of the process can answer, but is skipping this mod going to cause any major issues with the remainder of the guide? Additionally, if someone were to complete the rest of it and want to install this later when it is re-released, what would the process look like to get this installed into the existing mod list?
