What color is the stone when you place it? Blue, Green, Orange, Red? If its orange or red, that could be your issue, there's not enough support to keep it in place. If its blue or green, then, I don't know, it would be some other kind of issue or a bug maybe?

It was yellow and green, with orange at the very top level of the dome. But after the rain stopped the entire roof, supports and dome were all orange and red.
