We need a .sav file so that when you update, we can go to that folder to copy and paste our save file the new game version folder. That way we can still keep our settlements and continue from there.
Also, would like to see that when we create another settlement, we can nominate a new ruler for the settlement we just built. That Npc can be our ally or enemy and so we can do trade agreements with him/her. You'll see more allies and enemies to battle.
When you update Realm of Rulers it keeps your save as they are no stored in your downloaded folder.
Save files are stored in the hidden local appdata folder. Once you are in this folder there should be another folder called EconomyGame. Inside this folder go to the Saves folder and your save files are inside of there.
The save files are named ecsave0.2.2.sav (legacy support save), 2.sav, 3.sav ,4.sav ,5.sav, 6.sav. You can copy these to another computer to continue your game elsewhere.
To access your local appdata folder you can use this shortcut:
Having your citizens branch out would be a cool feature. It might be something we can include in the future!
