Hmm, so the clock ISN'T supposed to be there? Odd. Actually, after the train crafted and was waiting to be collected, there was no clock. It only shows up 1) in the Warehouse on the delivery order, 2) in the menu for the Toy Maker, 3) when it's crafting, and 4) in the Barn inventory.
Since the St. Patrick's Day event ends in a couple of hours, I'll try reinstalling this afternoon when I get home. As I said, though, it doesn't really bother me. It was just a point of curiosity.
