Fallout – Is it possible for dwellers to have twins in fallout shelter

Do you have many dead people in your vault?

Due to the fact, that a dead dweller can be revived even 24 hours after his dead, you cannot get above the limit with a new born child.

Just an example of that what I mean:

• Your vault maximum is 38 dwellers.
• You have 30 alive dwellers, 8 dead dwellers and 2 pregnant dwellers
• If the birth would happen, you would have 32 alive dwellers (of which are 0 pregnant and 2 children). You would have 6 dwellers left to your maximum capacity.
• If you would revive all of the 8 dead dwellers, you would have 40 out of 38 allowed dwellers.

Maybe this gives you a hint and maybe this is your case too.

The idea of the dead father won't work. I have also some new born which had a dead father. The icon of the father was just a grave, but it was found. The birth take place and everything else was normal. But well, it still could be a rare bug.

The only thing which could explain it (besides a bug) is that you may missing some electricity or water. If you haven't enough electricity your food and water supply will fall down and maybe collapse. This will increase the radiation of your dwellers. In some cases they may die on this.

Otherwise, I would say it could be a bug. I've had a situation which was nearly the same. In my case electricity was too low, which leads to the situation I described above.
