I was notified by challenge checker user about bug in list of Swiss counties (municipalities). I found out, that list of counties is not complete for Switzerland - municipality Reinach (AG) is missing.
Please, note, that there are two Reinach counties in Switzerland, one is in canton (region) Basel-Landschaft (this on is listed on project-gc.com) and second one is Reinach in canton (region) Aargau - this one is missing.
Both are distinguished by abbreviation of canton name in brackets after Reinach name:
Reinach (AG) needs to be added to list of counties under Aargau region, Switzerland.
