EDIT: Was *not* caused by this mod.
I recently installed SOD during a playthrough of BGEE (~70 hours in). I had Romantic Encounters installed. I installed DLC Merger, then reinstalled RE.
Now whenever I quicksave, I get a new save file that looks like the name is generated from dialogue (from RE?): "I am planning on seeing four corners of the world, but no matter if I go South or North, East or West, I doubt that I would find anyone more beautiful than you, CHARNAME."
After this save file is generated via the quicksave key, if I quicksave again I get a pop-up telling me that I don't have available file space to save. I guessed that this was due to the long file name, so I delete the quicksave file...then I'm able to quicksave again, but it just regenerates the same file name.
Any ideas on what's going on?
