Here I did a test on timescales: On each of these saves I waited and let the time past 8 days. Keep in mind, I loaded the original save each time I test a new timescale. Original Save - 3,876 kb Save 1, Vanilla default timescale (20), - 3,756 kb Save 2, Timescale set to ( 8 ), - 3,747 kb Save 3, Timescale set to (40,000), saved while timescale was still running - 3,841 kb Save 4, Timescale set to (40,000), saved after changing back to vanilla default ( 20 ) - 3,835 kb I used no mods and de-bloatifiers. It might be different for me since I have my Skyrim on 1.4.27 patch. (I don't want to switch back to 1.5) Try doing the same test as I did and see if you get similar results. File sizes changed back and forth but no significant abnormal jump.
