Helm's Dike - Defending The Watchtower (at least done in solo/duo knowledge) does not reward you with a medal.
I killed all Dunlendings, 0% damage to watchtower and no medal. This has happened 4 times now, and I think it is a problem. I sent in a bug ticket.
Just thought I would make a forum about it to get the bug more attention.
(P.S. Thanks for fixing Glittering Caves)
