So I have a problem I really need help on.

I'm currently playing Fallout: New Vegas and my companions are missing.

It happened right around the time I completed that mission where Benny was captured by the Legion. After I finished that quest, I fast traveled to the Brotherhood's fort, and noticed my companions (Cass and Rex) were gone.

They are still missing several missions later, but the game still acts as if I have them in my party.

Any help would be appreciated.
