I updated from an IPhone 5s to an IPhone 6s. I restored my fallout shelter game from the cloud. When this occurred there was a glitch where all my explorers in the wasteland somehow had survived for months. They came back with an amazing stash of weapons. However now when I send an explorer to the wasteland nothing happens. They can be out there for days but the log still shows 0:00. What can I do to fix this?

Is there no solution to this?
