Alright I had Cass as a companion for a better part of the game only because she's so darn cute but now she's disappeared and I have no idea how to find her. After I had Rex join the squad (it was done automatically when The King basically giving him to me) Cass is nowhere to be found. I can't even find the "dot" on the map, went to a bunch of places and nothing.

Is there anywhere to "recall" her or force her to leave my party so I can pick up someone else or if Bethesda could look into it that would be great.

she should be at the mojave outpost or lucky 38. Hope that helps
