Hi,

Thanks for mapping in Italy. Notably you've created multiple duplicate ways in town and the large circular at the west. The latter is actually not a roundabout as there are 2 stop signs in the ring. I've corrected that one.

Kindly take care of the duplicate ways in Catanzaro. Where they are exactly you can see in this map by OSM Inspector, the dark blue lines.

Strangely there's now e.g. an alley way on top of steps by the name of 
Discesa San Francesco di Paola. We can't have 2 ways on top of each other and why the alley is now on layer=1 suggests there's a bridge, but no bridge=yes tag (think ID Editor makes it too easy to just add a layer tag when 2 ways on top or ways crossing buildings)

Happy mapping & thanks
Rob

PS When mapping in Italy, please do your change set comments in Italian or English which most mappers understand, Czech we don't speak ;O)
