I got all my dragons to 10 and it said to build a dragon Tower when I did this the dragon Tower didn't work still says I need it but when I go into the shop to build another one says I already have it laid down now I'm not sure what to do

@Mike-Maddox I believe you need to be at least level 19 and purchase the Magic Temple. In order to build the Magic Temple, you will need a number of neighbors to help you. It will tell you the number when you purchase it.

@Mike-Maddox You have to be level 19 and you need 5 neighbors for the magic temple.
