I just blew like 6 enhancement cores when I didnt have many to begin with on updating my exotic Felwinter's Helmet. After adding mods, I clicked on it to wear it and got a message that it is currently unavailable. Was told to go to help,bungie.net. I just earned this last week from a quest, and I'm ticked I wasted enhamcement cores on it. Anyone know what the issue is, and is there a way to contact Bungie and ask them to restore the enhancement cores? Thanks!
