Empty cards maintenance deleted (what I thought were) non-empty cards

Hello Damien, and everyone,

I was playing around using the "conditional formatting" features in order to create a new type of card based on an old type of card. When I added a new card type to the existing format (sorry, I hope I'm using the terminology correctly), it generated new cards of that type for every card of the original format. I only wanted some of the cards of that original format to be the new format, which is why I set up a conditional format. However, even though the conditional formatting seems to be set up correctly, Anki had already generated cards in the new type for every one of the old type of card. These new cards were empty, however.

To get rid of these new, empty cards I used the tools>maintenance>empty cards dialog , however, in addition to getting rid of the new empty cards, it also got rid of the old cards as well for some reason, (i.e. nearly every card that I had made in that format) even though they appear to have been unchanged.

Basically, it took me a little while to notice that these had all been deleted -- I did look through the "these cards are about to be deleted" dialog, but obviously not closely enought -- is there any way to undo the operation? Or is it best just to download the most recent version from the server?

    You can either download from the server or restore from an automatic backup:

    If you want help figuring out why your new card type did that, please post a screenshot of one of your cards in the browser and of the Fields and card types windows.
