Uploading to the server failed because your current dataset violates a precondition. The error message is: ResponseCode=412, Error Header=<Precondition failed: Relation with id 80936 cannot be saved due to Way with id 9828077
"
After searching the OGF-data, I found that:
1.Relation 80936 is the FSA Land Area (which was changed in my dataset by splitting a way) 2.Way 9828077 was a coastline way in Arghenna.
Any help here?
