Hi I have managed to clear the "rise of rome" map and make so it has the base game rules and want to use it for the medieval era scenario but I dont know how to copy the rules of the scenario to the new map. Is that even possible? Thanks

I am mid game and realized that a unit in the mod is overpowered and cheap. How do I correct it. Others have been changed to above the normal max limit. If I click to change it, I cannot click out until it has been adjusted to less than the max limit.
