veronica is glitched, had her four a while everything was fine then after completing he companion quest she won't follow me, she doesn't appear upon fast travel but will appear several minutes later and enter into the dailouge she would have if i had asked her to speak, after exiting the dailouge she repates the whole doesn't move followed by the conversation. i've already tried firing and rehiring her but it doesn't help. anyone have an idea?

I am having the exact same problem but with Boone. maybe all human companions are broken? Rex still works properly even with a bad brain.
