OKAY. I admit I read about this on the Forums before but as I was not at that stage of the guide at the time I put it in the back of my mind and forgot about it. Below is a list of plugins that were Opened and Saved in the Creation Kit then Sorted and Cleaned in SEEdit: IcePenguinWorldMap.esp (A Quality World Map)Enabled Masters: Dragonborn.esm, Skyrim.esm, Update.esm Better Dynamic Snow - NSUTR Patch.esp (Better Dynamic Snow SE)Enabled Masters: Dawnguard.esm, Dragonborn.esm, HearthFires.esm, Skyrim.esm, Unofficial Skyrim Special Edition Patch.esp, Update.esm SRG Enhanced Trees Activator.esp (Enhanced Vanilla Trees SSE)Enabled Masters: Skyrim.esm UniqueBorderGates-All-PointTheWay.esp (Unique Border Gates SE)Enabled Masters: Dawnguard.esm, Dragonborn.esm, HearthFires.esm, Skyrim.esm, Update.esm RogueArmorHD.esp (UNP Rogue Armor for SE)Enabled Masters: Skyrim.esm NOTE: "SRG Enhanced Trees Activator.esp" and "RogueArmorHD.esp" don't exist in the final profile plugin list but these were the masters they had prior to merge. MY QUESTION: Which if any of these plugins have missing masters now? The instructions in "A Note about Converting Old Plugins" did not mention I had to "esmify" plugins prior to using the CK so I never even looked at the original plugin masters prior to using it.
