Warlock autokicked and logged out on spawn.

Is anyone else experiencing this?

Whenever my Warlock logs in, she summons her demon and then I get kicked out after about half a second to the login screen with the message 'You have been disconnected from the server'. I unstuck my Warlock from STV to Stormwind City and it still keeps happening.

I can login to my DK and Paladin and play with them fine. It only seems to happen on my Warlock. Any advice or fixes?

For background, I'm a donor and can bypass the queue.

Figured it out. Necrosis, a Warlock addon, was being stupid.

Disabled it and was able to login and play like normal.
