During my current install, when unchecking "Automatic Archive Invalidation" in Mod Organizer. I'm left with a checked file in the Archive List called "Skyrim - Invalidation.bsa". Just wondering if this should be unchecked or left as it is (or if I have made an error)? Update: Reinstalled MO and recreated the Profiles (ensuring everything was unchecked) and the file is still there.

A while ago (last year I think), the SR:LE guide contained recommendations for mods that would benefit from using DDSOPT. These have since been removed (due to the constant updating of the guide), and I was wondering if there was a similar recommendation list that could be used when installing SR? I apologize if this has been posted elsewhere, I did a pretty thorough search though .
