Any way to increase city spacing beyond 8

Hi all…again

I am trying to increase the city spacing above 8 but seems to be locked to 8 for some reason.

Even using the wild life start and having

city size = 1
city spacing = 8

I still see a lot of towns even though most are small but I would like a lot more forest etc.

I am using mods a few infact so this is probably the reason?.

It’s hardcoded to max 8. I’m not sure why, but I’d also like to be able to increase it much further.

On average how much does the distance increase per unit?
