I suspect node limit. Version 3 of <a href="https://www.openstreetmap.org/way/66564484" rel="noreferrer" target="_blank">https://www.openstreetmap.org/way/66564484</a> had 1937 which is fairly close to the 2000 node limit. Currently it looks like the outer ways could be merged without issue though.<br>
