I've come back to Skyrim after about 3 years away and completed the STEP 2.2.0 over the last week or so. I just wanted to say a massive thanks to the team who have put together this awesome guide, it's well written and thorough. So my mod list is exactly as described by the 2.2.0 guide (unless I've made a mistake). Everything is working brilliantly now, except for some large rocks/mountains in snowy areas across the map. They appear shiny and flickering, mostly black but sometimes grey depending on my angle. Hoping you could provide some advice about what has happened here. I've attached some screenshots to show you what I mean.
