I had 3 raider attacks in about half an hour super early in the game. I have like 15 dwellers, one of which is a kid. I don't have enough weapons for everyone and the damned raiders always succeeded and my vault went from a surplus in all supplies and 91% happiness before the attacks started to deep in the red on everything and 20something% happiness in the span of about 5 minutes after the last attack. Seriously. Horse [censored].

I agree Dave. Raiders are evil and must be brought to justice!

horse[censored]? What's wrong with horseradish?

lol

I had a similar thing happen earlier, though I'm not sure if Radroaches aren't supposed to do this sometimes: Infestation simultaneously on multiple levels. Lost four dwellers because I didn't have enough kit to arm/heal every room.

I was given a tip to avoid this. The types of events can't really happen if you aren't playing so in early game, play less. Hop in, collect your resources, level up the people that are ready, get out. Don't sit with the game open. Once you have enough weapons you can start leaving the game open more if you want. I have most of my dwellers armed now so when raiders attack they never make it past the first room they hit. I've also since added well equipped guards to the vault door, one has a missile launcher and the other an alien blaster. Will see how that works out.
