Druid Epic Rune crested BOWL

[Sakir]

I have Gathered the items twice now used two different pottery wheels with same error

the Ancient Pattern, Platinum Speckled Powder, and Enchanted Clay

Then clicked combine

Server responded
Server Error , Server does not recognize specified trade skill container , Kicked off server to login

Upon logging back in The Ancient Pattern, Platinum Speckled Powder, and Enchanted Clay where Gone from inventory and i did not have the Combined item Rune crested Bowl.
This has happened twice now.. so i think it is a bug

PLEASE help i already did the running around to gather items TWICE now.
