In a single session, if you use the "add multiple cards" button multiple times within a few minutes(as in rebuilding a session and importing your image batches into your various decks), the add multiple cards button will strangely tack on the last 1-8 cards from the previous deck you imported via the button. Its not a set amount, its random depending on the size of the deck so I believe the code has something to do with percentages or time to process cards. Before you ask me if I had some selected, I didn't. If you go into my account and look at my art folders you will very clearly see that I am quite OCD with my art organization especially when it comes to deck images. And yes, I will be posting a bug report about the art folder shortly too.
