Hello,
I'm not sure what happened here, but one of the ways https://www.openstreetmap.org/way/273992803 seemed to get added to some relations more that once - it looks like it was already there with role "outer", but was added again with no role, which seemed to result in the relations dropping out of a rendering database.  I've removed the duplicates, so the relations should appear again tomorrow.
Best Regards,
Andy
