Hello, dear fellow Users.
I have been experiencing problems with Anki for many months now. However, they just disappeared after a while or when I exported and reimported my collection.
Though, I have recently noticed that I have reportedly lost cards without accidentally deleting them (!), as I already did a couple of months ago. I have old backups, but since I do not know which and how many cards I lost, I do not know what I need to retrieve. Only some cards that I have clear memory of and positively know I have lost is what I can restore. Is there a way to compare an old collection to my current one to discover which cards have disappeared?
After (literally!) thousands of hours of work put into my decks for a very important and very difficult exam that I must prepare for 18 months (German first law exam), it is particularly painful for me to loose cards that might be essential for me scoring a good mark.
Most of the time, it says my collection is damaged. As I said, usually a quick export and reimport solved the issue. However, recently, I got the failure message enclosed, after I tried to create a card, Anki bugged and shut itself down, sending that text to me. Today, Anki refused to sync for a couple of times, but this then disappeared.
I am using Thomas Kahn’s German law forms and his Butler addon (http://www.thomaskahn.de/jura-vorlagen/#/download). Anyhow, the problems also occur when I start Anki holding shift key, thus disabling the addons.
PLEASE help me, my exam marks determine my future career and life, I really can’t afford to loose any work put into my collection.
