Hi again! When you saved this changeset you added what's called a "node drag", where one of the nodes that was under your mouse while panning the map got moved accidentally. It's easy to do – especially in dense areas like the train yard. You can tell it happened because the screen doesn't move when you expect it to. When it does happen, a quick click of the Undo button in the editor (upper right) will resolve it for you.

I manually fixed this one.

Thanks again for your improvements to the map!
