Random 25k+ cities in Germany on a map

Oh no! 20 random german cities, communes, markets and/or settlements have had their green nature areas been painted in black! Can you guess their names to restore the green?
Map from GitHub, colors and dots were added by me
City proper population figures from Citypopulation.de
This quiz took quite some time to make (For the map revision, I had to manually place each dot with the help of Citypopulation.de and Geodatos / Google Maps), so I would appreciate some feedback
Click the map to zoom (It can help you see which cities are located in what county)

nice! I think if you use this CSS code in the quiz description, only the randomized cities will show up on the map:

<style>.zoomable-circle { visibility: hidden; } .svg-holder .random-svg-highlight { visibility: visible; fill: #ff9900; } </style>

Thanks for the suggestion! I added that text to the quiz. I wanted my quiz to have that, but I didn't know how.
