Technical I have a green "thing" behind my character

[Rotiv]

So I've been using WOD's models for 3.3.5 on Lordaeron's realm and all of a sudden it started appearing this green thing behind my character that persists even if I stop using the updated models and even by deleting Cache folder.

What do I do? No other character of mine has this issue and it started after the restart that occurred a few hours ago

Best thing I would tell you is try to reinstall the WoTLK client (or remove any other custom patches).
Some other ideas could be possibly the GFX card isn't rendering the game correctly so you'd may have to play with some of the video settings ingame. If all else fails, try a nice hard reboot.

Hope it helps,

It might be because of the maintenance. Did you try to log on the character? Is it still there after you log out? It might be caused by some specific item you have equipped.
