Hmm...I just finished Legacy of the Dragonborn V18 old version. It's final quest was extremely glitchy. This made be think about restarting my character with all of my current mods updated.
Right now my 450hrs save file is 43 mb. I installed and uninstalled countless mods mid game. Initially I wanted to restart my character when beyond skyrim is out, but I don't think I can wait that long. On the other hand I don't want to restart because I have completed SO many quests using my current character that it is unreal, I don't think I will ever have the time to redo those quest mods again. Think.
