Heroic Mode - Problem with Event

First post of 2017 - doesn't say much for this message board, but I don't think it appropriate to rant on Facebook about these things.

I completed all the Heroic levels and collected the Starcrystal Fragments. Crafted the first armor, leveled it to 35. The crafted the Plus version. No big deal, typical.

I had time so I did the first Hardcore board just to get the Chrono Cores. Finished after waiting for a couple of healing time outs.

When the event ended - the system took the Chrono Cores back saying "they were unused Star Fragments" and gave me whatever for them.

What bull. Maybe someone should look into this as this is not how the Hardcore levels are presented. I understand that the Star Fragments come out every Heroic, but specific materials should be allowed to be kept for future use.

Thanks.

My apologies to Gree.

I see now that I have finished crafting the Plus version that I was indeed awarded the Chrono Cores. I didn't have a free blacksmith to see my inventory of materials.

But, I was also given some items for uncompleted Star Crystals - a glitch?
