xxxpotatosxxx I don't play sky-block but i do play survival. I've had this happen to me all the time. The blocks dissapear but they are still there when you click on then. The way i made them come back again though is i took out the coal block and put it back in or the mineral. Its not an official fix but it works. Hope this helps
