I was putting together my AT-TE yesterday and was short shipped 4 pieces. They were the darker blue squares that have 4 things on the top, that go on the back of the legs. I made due with out doubling up like the book said to, but it is kind of annoying that they shorted me 4 pieces. Has this ever happened to anyone else? And if so, what doyou do? Will Lego ship you the pieces you need?
