Retrieve the Relics- Bugged?

[fabo12]

Hi guys, hoping for a little help for a simple mind here.

I'm on the quest to retrieve the relics in DF...I have stepped through assaulting and capturing Mjollnir Castle, went through the portal, clicked the port to go to and from Lohtelkehk...

I have tried to loot all of the relics, but every time I try to pick one up it says "You can't get that!"

I have dropped the quest and retried it three times, to no avail.

Does anyone know of this issue, and how to remedy it? Or conversely, is there a workaround to further the quest progression?

Thanks much for your input!
