Too many city/townships in my state don’t exist in my app

I’m trying to size compare my city in Ohio but they don’t have it (Dayton) and it’s frustrating I also like trying to load all my states city’s but there is just too many not existing in the app

It’s a little fun but…

I was playing and dragging countries until the screen that says “would you like to start fresh or continue session?” so I give it 4 stars.

One thing…

U CAN USE THE REGIONS AND HISTORICAL COUNTRIES but I have four suggestions
1. Newly historical countries to have normal flags and not just stripes
2. Older historical countries to have flags
3. Historical countries to have subdivisions shown
4. All states to have flags

CHANGE SOUTH AFRICA SO IT DOESNT INCLUDE LESOTHO

Why does it show Lesotho as South African when it is a country

Yay

Little laggy and have russia have its 85+ subdivisions and have the vs thing on it unlike the website other than that good
