I'm having a glitch that is basically what the title says. Veronica is definitely following me, but when I exit the Ultra-Luxe she stays in there, right inside the door. I also have Rex but he follows me out. I've tried having her follow/unfollow me, going in and out, going through other doors, etc. I've also tried the console command that's supposed to put her in front of me but it doesn't seem to work..
Has anyone had this happen? What should I do to fix it? Btw this hasn't happened before. And if it matters I did tell her to wait at one point in the Ultra-Luxe, but she followed me after and it seemed normal.

Try dismissing her to the L38

Sometimes fast traveling puts things back on track too.

Wow I'm so stupid haha. Fast traveling worked, I really should've thought of that before..

Also, sometimes going out a different door will work too. I come across this at McCarren using the Westernmost doors where companions will not always follow me. If I use any of the other 3 sets of doors, the companions will go through.
