Many thanks to the STEP team and the entire STEP community for all the time and effort you continue to devote to Skyrim and this guide!
Just finished following the current 2.3 version and it went rather smoothly. Only in a few places was I initially unsure of the instructions, but after re-reading I was able to proceed confidently and everything seems to be running beautifully so far (though admittedly I haven't done much in this new build yet).
I did notice one small omission... the instructions/recommendations for Glacier LOD Meshes do not mention that this is a SkyrimLE mod and to ignore the MO warning indicator, as the guide does for other such mods.
