ERROR 311.... How to fix?

So, every time I launch wow, it crashes anywhere from 3-10 times after it finished loading after "Entering World"... It gives me Error line 311 or some other random errors... Anyone know how to fix this? I'm using Legion creatures patch along with the normal Warlords of Draenor character models provided by Warmane. I thought my addons were causing it, so I did a reinstall on all my addons and replaced half of them. It was working better, but it just started crashing again and I don't know what causes it.
