Just noticed this today. Done a full scan like 2-3 days ago and the total file amount was 300-330,000 give or take but when i ran it today it was over 450,000.
Thought it was odd but then i realized that its always been kinda like that, for me anyways. Is it normal for such a difference with total files scanned? I also havent downloaded anything recently to make the results change so drastically.
