It might be time to make adjustments to your favorite tracking macros, guys. As Cangoc over at World of Warcraft forums explained, something was up with his character's ability to tag target characters up to 60 yards away. Here was the player's full explanation:

This may not have been a recent change, but I remember that at 60 tab targeting almost always gave me the guy I was trying to get a hold of. Now it seems like it goes out of its way to pick the wrong target. I get guys behind me, guys way off through a wall, etc...anyone but the guy who's right freaking next to me who I'm trying to target.
