Recent changes to handling of building relations, heights and roof orientations causing incorrect output?

[chram2]

Hi there,
something must have changed during last year. What worked fine in the past, now doesn't anymore. Though I can't find a cause and no changelog entry.
Some building relations are ignored now and the outline of the building is rendered and covering the building parts.
Also the roof orientation of gabled roofs is twisted 90°.
Moreover it is noticeable that buildings without height tag aren't displayed consistently but very different, some high rising, some very low.

As said, one year ago, that worked fine. Other 3D viewers like Kendzi still show them correctly. For example at this location:
https://osmbuildings.org/?lat=48.49078&lon=9.21106&zoom=18.0&tilt=30

Relations of buildings in that location: https://www.openstreetmap.org/relation/10120299 , https://www.openstreetmap.org/relation/11277955 , https://www.openstreetmap.org/relation/10120301 , https://www.openstreetmap.org/relation/8404390

Could you find and help me with an explanation?

Regards,
Chris

Hi Chris, Thank you for reporting and all helpful details (rare these days).
This is likely connected to a switch in our data sources. I'll take care but it may take a while to debug.
Thanks,

Hi Jan, thanks for the quick response!
Now I needn't brood over that any further. I'm looking forward to the update!
