For the past week or so, adding items to my wishlist from the vending page creates duplicate entries in my wishlist that I have to delete when I go to sort them into categories. This doesn't happen anywhere else that I can tell, just the vending machines. I use FF 31 and Windows 8.

Confirmed with a test just now. It has been a while since I initially made this thread, so I'm not surprised that it's been fixed in the interim. Thank you for checking up on it. ♥
