I have messed up water probing as well as brigdes in roads.py up. Please do not pull from git until it is safe again. (I guess that stuff up until https://gitlab.com/fg-radi/osm2city/com ... 9d6a7da373 is ok).
Unfortunately I did not find this stuff when working with Iceland - but not working in Switzerland it looks worse than previously. Sorry. Not sure when I will fix this, as I will be on vacation for three weeks.
