I was stupid enough to tell Rex to go back to the Lucky 38 while still in The Fort. Now he is stuck there haha, anyway of fixing that? Im on the 360 so console commands wont help:)

You can't find him after telling him to go away? If he's still at the Fort, go back and recruit him. Then try fast traveling, that is if you're not hated by the Legion.

I find at the fort and when i try talking to him he just barks at me, I think I screwed him up. Probably not fixable on a 360
