I intend to redo the conflict resolution patch manually, following the given instructions, except obviously skipping the bits that involve Immersive Armors. I *think* there were some other patches as well to get other mods to play well with Immersive Armors. AFAIK though, the base SRLE build involves the Conflict Resolution patch at the end, and that patch includes the esp from Immersive Armors as a master.
I'm going to redo my SRLE build, and this time I'm skipping out of Immersive Armors and most of my current armor mods, opting for The Book of UUNP instead. I suspect this is caused by some meshes from Remodeled Armor. I've also noticed weird artifacts with some NPCs wearing certain pieces of armor, causing 'floating' pieces of armor to follow them around. Thing is, I don't like or don't care for 99% of it. I'm around 20 hours into my current gameplay, and just for testing I used console cheats to pump the Smithing skill (so I can see what armors are added by Immersive Armors).
