Rise of the Machines BRD Quest

[ebashuvkashu]

Got all parts needed for quest: Head of Argelmach and 10 Intact Elemental Cores. Quest is marked as completed in quest log. But I can't complete it with a questgiver, which have a silver "?" sign above his head. Maybe it's because I had 11 Intact Elemental Cores and I deleted 1 core, because only 10 needed for Quest?

Try to put the quest items into your bank, log out and back in and then take them back out.

Your quest should be able to be completed then.

Thank you! It worked.
