I got a window asking me about one conflicting tag (the street name), no surprise because this was the reason for my edit, so I correct it from the suggested ""A;B"" to ""B"" and continue.

(I do ""synchronize whole dataset"").and it turns out that 16 conflicts are reported, all happen to have to do with this routes. I go to conflict resolution and choose 16 times ""my version"". On the next upload try I get this: ""Uploading to the server failed because your current dataset violates a precondition.
