Ever since the patch, I have been unable to get quest updates on this character. I have two other characters that I did the daily quests with last night fine, but this character does not get any updates - nor quest drops required by a quest. I had hoped it was just a problem with dailies, and it would be fixed when they reset, but this is not the case.

Anyone else even heard of a problem like this before?

Check and make sure you're not still in a raid group.
