This is what I got when I went to send stockings just now - not sure if they were sent, but my tokens were taken ......

JSONParseError: Unexpected B 66 encountered Invalid JSON - Parse Error[Buy Buddy Store Item {"success":true,"notifications":[{"message":"I sent you a Christmas Gift in Egg Breaker 2!","data":{"holiday":"8","gift_id":"16","user_gift_id":4,"from_user_id":"1322"},"to":"694411720","notification_type":"user_request"}],"processing_time":"0.0182328224","apc_stats":{"gets":13,"gets_time":"0.0000820160","sets":0,"sets_time":"0.0000000000"}}]

I got it too, but the stockings actually did send. When I checked my play history the stockings had been sent and when I returned to the event page the stockings had the check mark on them.
