Guild Wars 2

This is still not fixed as of today’s patch (June 3rd).

I just tried to do the same thing. Can’t upgrade mine either. I have a suspicion that the new item is actually a different item then the old one. If I remember correctly the old Sclerite Karka Shell had an Unused Defensive Agony slot even when it was exotic, which was weird. This new/returned version has what you would normally find on an exotic, an Unused Upgrade Slot. Perhaps this is why it’s not showing up as being able to be placed in the mystic forge – because it is a new item and no recipes exist for it so it’s grayed out. Maybe Anet forgot to add the recipe when they added it.

I have the exact same problem. I was so happy to see this reward return as I missed out on it the first time. Now I find out I can’t upgrade it to ascended I hope they fix this soon.
