I was talking about not receiving 600+ science points on this thread a bit ago, but it turned out for some reasons I thought it was invention progress, I'm sorry for any inconveniences were caused, I did recieved the science points 
i wanted to tell you, i saw no problems with that big event
But can I ask what will happen if the number of active ref run out? Bc I'm having 10k sat now and I'm thinking of either buying a ref or upgrade my pub and I want to know if there wont be any ref to buy if it run out.
Thank you
