Mapped shapes match neither basemap.at nor satellite images. Unfortunately, basemap.at and satellite images don't match perfectly either. This probably requires on-the-ground surveying.

VS 4 has been mapped twice here.

a: node/1445264868
b: node/5599177524

I would normally just merge these and apply fixes as I see appropriate; however, in this case, the two nodes have disagreeing values (wheelchair=yes and wheelchair=no). Before any fix can proceed, we might want someone local to survey it. I don't want to merge it and just drop accessibility information for the sake of deduplication.

Intersection was rebuilt into a roundabout.

Speed limit is now 30 km/h, but I don't know exactly where it starts or ends. I might be able to do a survey in a few days though if nobody else beats me to it.
