In Fallout: Shelter, you sometimes get objectives with conditions that are already satisfied, such as:
Assign X dwellers to the right room
This objective is detailed in this question, and appears to be a hopeless case. I recently got the above one (which I removed, since I wasn't ready for a growth of X+ people), but immediately after I got rid of it, I got the following:
Have 1 Bald Dweller in the Vault
I already have two bald dwellers, but the objective doesn't trigger. I've tried sending one of them out to the wasteland and recalling, without success.
Waiting for a random bald dweller to show up could take a very long time, and isn't reliable. Another way would be to breed one, but I'm not sure if I can affect the hair of coming babies in any way (do boys inherit baldness from their father?).
Is there any clever way to complete this objective in reasonable time (through some trickery and/or breeding)?
