Something very odd just happened in my game, I had Santa arrive one day - cookies made, house decorated and Santa left them a present. The next day no cookies house, still decorated (I like the tree so left it all as it was) got to 10pm, jingle bells sound, and santa appears

checked all round the house there are no cookies anywhere. Santa left me a lump of coal with a message about how next time he'd like some of those nice cookies.
On a mission now to find out what why he's turned up again, could be one of the decorations, the tree has now been sold and I'm off to see if he turns up again
