I have just reached level 50. I placed a storehouse on the island that has just appeared to the south of the home island and found the Iron mine. I have defeated the first group of enemy camps. Why can I not build on the new section of land? All I can do is the storehouse and 2 generals on that land. I can not even transfer the generals to the new section of land so I can get closer to fight the next group of enemy camps. Do I have to defeat all the enemy camps on the whole island first before I can start building?
