How do I get Cass to use a different gun? She seems to be stuck with that shotgun she's using. I gave her a fully repaired Caravan Shotgun and ammo but she won't switch to it. I also gave her about 40 sticks of dynamite and she won't use it. I gave her a fully repaired Cowboy Repeater and ammo and she won't use it.
Are these not better than what she's using? Or will she just not upgrade? Or what weapons will she switch with?
Thanks.
