Hi,
The change was made with the tool Relatify, bugs introduced by this tool should probably be signaled in https://github.com/Zaczero/osm-relatify/issues
And maybe the tool should be turned off if its behavior is not correct.

Not sure what you mean by "destroy" I don't think I've deleted any ?

Regardless, please let me know more precisely what the errors are and how to fix them and I can probably have a look.

Cheers
