Around a Gig free, it's a glitch that usually pops up after long play periods.
Example, I was playing and decided I need a nap, well I napped for eight hours, once I got up I saw I left the game on. Since I'm addicted to saving I try to quicksave before I close shop. Says I don't have the space, save in different slot, same thing so I go in and delete all my extra saves till all I had left was the autosave, still not enough space. Restarted the program still get the glitch, restarted my computer it goes away for a bit.
I've noticed it happens fairly reliably in certain places the earliest at the inn where you meet the dwarf.
As of late it's always on.
