Safety Deck Visual Bug

I was testing the safety deck, to understand how it worked, and sometimes when I placed a card there was a visual bug that the card image wouldn't leave the screen, the only way to solve the bug I found is to refresh the page. (Sorry for any english mistakes, it's not my native language.)

This is a bug with cards in general.  I will also piggy back on for any card related dev who sees this post that the bug involving the mass uploader still exists, if you upload many things in the mass uploader, and then rapidly upload another set of things as fronts to a deck, part of the previous group get added onto the newest batch uploaded, even if they are for different decks.  The only way to prevent this is to only use the mass uploader with a healthy chunk of time between uploads.
