Hello!

I was hoping the new patch would fix my problem, unfortunately my problem persists:

"Volare" Quest: I have to fix that sunken plane, but I need a device in order to stay longer under water. The quest guy, Jack (He's blond in case you don't remember him), he suddenly switched to hostile mode when I brought him the needed item. Since then I can't talk to him, he keeps threatening me with his knife in his hand, but he doesn't move. And this is an important quest, I can't just kill him or skip the quest, what could I do?

In addition, since ED-E is following me, several NPC's are yelling "watch out!" when I come close to them, it's weird. It think this is the same script that turned Jack into hostile mode.

Kill him means you have to kill all the boomers.

That means not support of the attack of Hoover dam, if you do kill all the boomers you do not fail the quest it’s simply an alternative to complete it.

you can still complete the quest without the device to breath underwater
