21068	[Patch] Flat roofs with roof:height	Friendly_Ghost	team	I found that nearly 7,000 ways in the DB are tagged with both roof:height=* and roof:shape=flat. Some have the redundant value roof:height=0, but many have other values, even negative ones. This has already caused https://demo.f4map.com/ to crash when looking at the city of New York. Could this combination of tags be flagged as an error?	enhancement	closed	normal	21.06	Core validator		fixed	roof height	Klumbumbus
