I have a noble temple, but I haven't paid my 30 gems to open it yet. I am lv.30 and I bought a Knight temple, but it isn't done building yet. (It's 24 hours .__.). Do I HAVE to pay the 30 gems for the noble temple before the knight temple becomes effective? Or can I just get rid of the noble temple and use the knight temple instead? Because I have 92 gems, and I am saving for Ivory Island. So if I can avoid spending 30 gems, I will.
