Incorrect draw animation for Nemesis Staff

[srmalloy]

At random intervals, it appears that the draw animation for the Nemesis Staff power gets confused; instead of the normal 'pull it out of hammerspace' animation, you get the same animation that you see with NPCs pulling a tailpipe and muffler out of the ground -- you reach down, the shaft of the Nemesis Staff appears pointed at the ground, and you visibly strain while pulling on the shaft as the head of the staff gets pulled out of the ground. From casual observation, I don't think the animation time changes, it's just an odd-looking animation, particularly if you're flying.
