Hard Node Refresh Cost Decrease not working

I am aware that this is what should be happening, but it wasn't happening for me.  I was directed here after starting a trouble ticket.  The first was closed because I was sent troubleshooting instructions.  I opened a second ticket when that didn't work.  They were able to look at my activity and see that my refreshes were at the regular gem amount.  I was the first person to report the problem, so they said that posting here might help kickstart responses.  I've just reopened the game now and it's finally showing the discounted refreshes.  I don't know what corrected the problem, as it was there all day today until this moment.
