Not sure how I managed to leave off my description of the change. Leaving a comment here in case someone wants to know.

I removed the duplicate parking pin. Added a handelsträdgård I found on a walk, plus two gates/barriers.

I noticed this said it was going to change some bus routes? It's just a no left turn out of the car park, I don't think it should impact them.

I will add a better description in the future, I was under the impression the maproulette description was sufficient.

This is actually from bing, not local knowledge. I had JOSM misconfigured.

Jag visste inte att det fanns ett "track" alternativ. Det skulle passa bätte till vägen. Tack för hjälpen

JOSM warned about an empty role and role of member not matching with regard to the associatedStreet relationship between Main Street and the building with 37 Main Street Cafe.

I can't quite figure out what the problem is or how to fix it though.

No problem. I had found that out but I appreciate the help anyway! I'm fairly new at doing any sizable edits (such as adding buildings) so do let me know if you notice anything amiss.
