After the Holiday Party 2012 ended, players could have still donated coins using the station, unlike previous years, where it was only possible to donate during holiday parties. This was soon fixed.
On English language servers, after the Holiday Party 2013 ended, this item had the same message when clicked on that was there last year when the Holiday Party 2012 ended - "2012 Coins For Change challenge is done!" - despite the Holiday Party 2013 being the most recent Holiday Party. On other language servers, the message correctly says the Holiday Party 2013.
