Servus,

thanks to iD and its inability to sort route relations correctly, some things have messed up now with buses 901, 902, 903 and 904

Those bus routes are quite complicated and sorting them manually is not easy. iD always fails trying this automatically.

Such errors pop up when iD splits ways and tries to keep the sequence of ways in route relations.

JOSM is a better tool for those tasks.
