I spent a fair amount of time on Intellivision last year, even writing descriptions on why some entries were different in case they appeared to be duplicates to some. Now I noticed many are all gone. Maybe someone thought they were dupes but in some cases both versions are gone. For example, I see Triple Action from Mattel Electronics in my collection but I originally had the Sears one in my collection. Although I never titled them differently when adding them, I did fill in the publisher as Sears. I also added games with and without licenses. A game that has both entries gone is Chess and USCF Chess. I thought I entered them in October but maybe some were in early November and would have been part of that data loss? I did go in alphabetical order though so most likely I worked on Chess in October since I own that one rather than USCF. In any case, if it's part of the big loss then I guess everything is gone for good, but I really, really thought I had these in before the cutoff of where the data was lost
I thought I only lost the items I added for more recent systems. Any chance something else could have happened?
