There are a large number of validation errors today on Edinburgh bus routes which I suspect may be due to some of your changes. For example:

{"relationID":946200,"name":"Bus 5: Hunters Tryst =\u003e The Jewel","validationErrors":["ways are incorrectly ordered - https://www.openstreetmap.org/way/482837515","ways are incorrectly ordered - https://www.openstreetmap.org/way/482837515","ways are incorrectly ordered - https://www.openstreetmap.org/way/66111779"]}



Editing bus routes using the iD editor is generally a bad idea because it's not been programmed to understand them. I'd recommend something like josm instead.
