182 hours for a radio station to call in settlers?

The game says it will take 183 hours to call in a dweller using a radio station in Fallout Shelter. I used my iOS's clock to forward time. I tried destroying it, but it didn't fix it. Help!

Yeah time glitching breaks radio station, dwellers return to the shelter times, training stats etc.

The only thing it does NOT break is resource gathering from the buildings (simply because you can skip the time when you rush the room) and dwellers going out to the wasteland.

It can't be fixed. You have to wait for the time to pass and not time glitch meanwhile too.

Try assigning high Charisma dwellers to the Radio Room, it should reduce the call time drastically.
