Hi, and thanks for your contribution! Since you requested a review, I looked over your changes. In this case, it seems to me like you meant to add an apartment complex (meaning the outer area) but you actually added a very large apartment building. In this case the critical part is building=apartments. That should be landuse=residential, residential=apartments.

Let me know if you'd like me to change that for you, or if you have any questions. Thanks again!
