I'm doing the Dawnguard Questline as a Vampire right now, and the very first radiant quest I was given sends me to a Barrow in SOLSTEIM! I don't even get an arrow on my map. On a hunch, I made the trip to the island and BOOM, there was my indicator arrow and the Barrow.

Now that is ..... strange.

I have a similar situation with another character searching for upgraded crossbow schematics. I didn't think to check Solsteim for that quest, but now I think I'd better.

Just thought everyone should know that a quest location they expect to be in Skyrim just may be over on the island.
