Gotta repopulate the Earth I guess
I still go back to Fallout Shelter every so often in a casual capacity (it’s mobile, am I right, yuck yuck), and one of the things I’ve noticed is that it takes a long time to make a baby, which can severely impact the pacing of the game. It turns out that it’s a glitch that caused many mothers to just never give birth — that’s weird on so many levels.
Bethesda has addressed this with the first major patch for Shelter, along with a photo mode, and crash fixes. The Android version is still in development.
