I've killed this static DJM 1000's of times and know it extremely well
I usually leave my character logged in. And now I notice this.
But 10 min ago I logged my char out for over 3 minutes and it fixed it for 1 spawn so far .. so I'm still trying to figure out the exact reason its occuring
..
Also I'm not sure if the change was intended to change it's appearance every spawn, or once per server.
Currently it's changing it's appearance once per server reset.
