I started up the game just now and discovered that in addition to multiple cases of radiation poisoning, their health bars are extremely low.
I used up all the RadAway I had treating and retreating them and I ran out of MedShots a long time ago.
What will happen if this continues and the entire Vault reaches 0 health at the same time?
I don't think I have the required credits to revive everyone in it at once!
I can't even explain the radiation poisoning, there is no reactor and only 3 power generation rooms.
