You’ve created more than 50 changesets while working on the Interchange in the last 24 hours. Perhaps rather than trial and error, you could ask for help from the community. There’s a large number of issues I’m seeing here. Why was the original leisure=park multipolygon deleted? It may have been replaced, but you’ve managed to lose tags in the process. Way 1257869091 clearly isn't a separate building, it's a part of the Interchange building as a whole. A lot of this seems to be tagging for the renderer.
