1. Once I pass 50 dwellers, for some reason, the game seems to remove dwellers from my list without explanation. Ive gone from 52-49 overnight and 51-49 overnight. Is this intentional? Is there a "Logans Run" whereby older dwellers just get nuked and I havent noticed?

2. Assign dweller to correct room. I have 25 dwellers. They're maxed to 10 in all 7 SPECIAL categories. Yet no matter where I assign them, that quest does not credit me.

3. Random Exploring. if I take 2 x lvl 50 dwellers, give them the same weapon, armor and train both to 10 in all categories, then send them out in the wastelands, one will inevitably survives 2-3 days longer than the other before they have to be recalled. Is exploration a pure RNG on what they encounter, since I would expect both to survive the same length of time (or similar time) but theres always a massive imbalance within 24 hours.
