I rollbacked my Skyrim AE to 1.6.640 and reinstalled the mods I used that work with 1.6.640. My question is after I sort my mod order in LooT do I clean up the core plugins with SSEEdit like Dawngaurd, Update, Heartfire esm's ect ? If I do , does it not update Skyrim to current version today? Should I just not clean in my plugins. I have 9 dirty plugins. A few of them are creator mods, but the majority are the core one. Anyone?
