The map generator don"t generate maps without citys. In A20 it was ok, because it was possible to generate a map without citys and wildernes POIs. But not without citys and with wildernes POIs. Now in A21 the generator crash if you set citys to 0.
Sometimes i like it to play without citys and trader. Only with the lonly POIs. Its pure survival and fun to build all tools and horde base a bike or car only from mining and salvaging. Further i dream for the option to begin in a random spot. For me its boring to begin every time in the same biome close to the trader. Random or selectable by biome. Now i do it by myself by clicking the right mouse button on the map on start.
