Hello everyone,
I have noticed something strange, and highly worrying for me being close to my big exams. Decks that I created go missing and subdecks within those decks are put in other random decks. Why is that so? What is the issue, and how can I fix this? Also, this happened on both the iPad app version and the Mac desktop version.
May be of importance: I find the main decks title in another deck, but empty, while the subdecks are split to other decks as described above.
Many thanks in advance.
PS: I have the latest Anki version installed.

Please use Tools\>Check Database, and see if problems persist after that.
