Art of War Booming challenge Bugged

After the latest update I have found that the Art of War Booming challenge will only let you click up if you build a castle, rather than just two castle age buildings. Last few tries I have built a University, Monastery and siege workshop but the imp button did not appear. I then stayed in the game and built a castle and only then did it let me click up.
