Hello, im just back in the game after years and on my main char i dont get this "would you like to group up with your teammates from the previos mission" thing after i have completed a mission. It works perfectly fine on the other 2 chars i have but my main the oldest one doesnt get it, never. Is there any way to turn it on? Ive searched everything in option etc but found nothing. Glad for any tip or suggestion. thanks.
