Hello Helen, and thank you for your contributions.

As you can see in the following link, you've added quite a lot of nodes that don't seem to serve a purpose. Although this is not a critical mistake, it's adding redundancy to the map.

Note the "yellow" nodes, those are your new additions. Some of them don't really do anything because they're added on a straight line.
