@Garfieldwxg55 I was able to recreate the glitch and got the f3 screen shot.
If I see it happen again I will. I've only seen it happen once or twice and this was the first time I thought to report it. Also the error did not reappear with other zombies when I attempted to replicate it (I did not relog at any point).
