I've been playing it a few days. I think I found my first game breaking glitch
I'm on the side quest at the dinosaur statue where you find out who kidnapped the sniper's wife and then have to take them with you in front of the dinosaur so the sniper can kill them. I talked to all the people and found out who did it. But when I go to talk to her, I don't have the dialogue option to get her to follow me. I've tried putting the sniper beret on and off. The option doesn't come up.
