I'm wondering if anyone else has had this problem, and how to fix it. When I send my dwellers out into the wasteland absolutely nothing happens. I sent one dweller out for 8 hours and still nothing happened to him and he didn't bring back anything.
Did you turn your phone's timer ahead for some reason? Chances are that is the cause of your issue if you did. If that is indeed the case, I am not certain of this but, after the amount of time you jumped passes your explorer should start encountering creatures and collecting loot again.
