Just to be clear, is this a specific issue with the card or the issue where a disconnect/concede won't notify the user in any way?
It seems to have been an issue with how the client understands the messaging about how cards are attached to other ones. I didn't work on this bug, so take this with a grain of salt, but I think Journey to Eternity transforming and thus stopping being attached to something caused the next time we made a new attachment to be handled incorrectly. #wotc_staff
