I've seen pretty much every town size and distribution now, split - I've had cases where finding a town with over 700 population to ship goods was no doable

Default settings on my WR runs match screenshot as well so I would go in the same direction as meiqueen. I would then not move said settings (towns and etc)

I always have set mine to whatever it landed on after clicking on ''reset all values'' ie. I didn't change anything. I have no clue if it is an option or not
