Although I have already discovered skyshards on one map location, my achievement list shows that I have not discovered it yet when in fact I already have. Anyone else having problems with this?
Are you sure your looking at the description for the shards you found at the spot you found them in? They are not always easy to match up. There are also a couple of shards that are real close to each other, but one is underground, and one is above ground.
Use this map to make sure the shard your asking about is the one you found
