Recently, I've started adding cards to Trello by dragging web links to the list. This appears to work fine, but when I move the new card to another list, about half the time the details of the card, (title, description, cover, etc.) are lost and the title is replaced with the link as text.
What is odd is I haven't figured out how to reproduce it reliably. I just dragged 17 cards I had created this way and six of them corrupted as I described.
