I built a recording studio in sims freeplay but after i check it, it said that i have to wait for negative 40seconds although it says that it is 100% complete. It also said that i need to pay 2 billion simoleons to instantly finish it. And since its construction is still on going i cant construct another building. I am really hoping that you can do something. Its fine with me if ylu need to demolish the recording studio but i dont wanna reset the game. Ive been playing a long time.
