You have two, significant bugs that prevent me from being able to complete collections. I have bugs filed against both issues.
The quick sell bug is preventing people from selling the Scott Hurst card that just got introduced into the Cardinals collection. There are over 388 orders for that card, currently. With the latest code release the ability to sell cards has been turned off/disabled, even if one tries to sell it. The "on click" code is not working when you try to sell a card. This bug is preventing people from being able to complete the Live Series Collections, and also cost players money as they can't sell stubs for any duplicates we have. The issues is seen on the Xbox version of the game w/ the latest patch released on Friday.
If someone has a duplicate of the 42 collection cards, they can't get all 42 cards. I have two, Sixto Sanchez cards, so no matter what I can only get 41 of the 42 cards so I can never complete the collection until you fix the issue on your side. I completed the collections, and won't be able to get the Jackie 99 reward. Frustrating ....and I alerted you to this issue over 5 days ago and still hasn't been fixed.
