Isn't that resource stations? We already got those! 😊 There are three different resource stations, they all give one of the three main resources (coins, personnel and supplies) and they have a timer of about one week. They have a low low chance to spawn whenever you use the flag buttong but have a much higher spawnrate when your base levels up. I'm sorry I don't have any screenshots to give you at this moment to see what you are looking for but they will appear on the map
