"Thank you, Lego Quality Control, for being so proactive. When I opened the box, the first bag was a small, unnumbered one, with 13 identical light gray posts. I looked at the back of the instruction manual, and saw that there are 13 pieces of #4211389 in this set. As I started building the set, it became clear that these were replacement parts for the ones in the numbered bags, because those parts were the wrong shade of light gray – way too light compared with all the other sizes colored light gray. Thanks for recognizing the problem and addressing it from the start. This is a nice set, architecturally consistent with most of the other buildings in the series. The birch tree (including nesting bird) is a great feature, and the building colors and various details make this an enjoyable build. What I really appreciate is that each building has its own base, so the buildings can be easily separated and rearranged with other modular buildings in the series. I just wish the buildings extended deeper in the back, so we could have had more interior space. There’s too much empty space on the rear of the base plates – it makes the buildings seem a bit small. Nonetheless, this is a great addition to the modular building series."
