Hi DareDJ,

You moved the outlines of buildings and put them on top of the roofs. The roof is not the right place for outlining nor is this the right procedure in The Netherlands. In The Netherlands ALL building outlines come from Kadaster (the land registry). You can find this area here:

Would you be so kind to revert this change? 
Thanks.
