As an end-user I like to keep things clear and straight-forward - currently (I'm using 48 release) I am noticing that even though I make a custom Content List called "Active" the Launcher insists on putting its dated list name in place of mine. Now - I don't know what to make of that.
I set my mod build up, ran Navmesh under my new cloned list called "Active" - this was with the intent that my new play-through was all wrapped up and tied with a little bow. After Navmesh updated, I closed the launcher and when I came back later - the current content list was the dated one again - not my "Active".
