How can I contribute with data fixes?
First of all thanks for the project, you're saving me a lot of time :-)
I'm currently trying to make sense of the data, using Germany as an example. For the most part the data is correct, but there are issues here or there. E.g. relation '310385' lists the relations '-569767,-51529,-51477' as parents, but not the immediate administrative parent ('27026').
I'm not sure how to fix this. Is there a tag in OSM missing? Do I need to change the relation borders?
