(Shelter 169/188 population, 2, 3 depending out in the wild, all rooms properly filled and powered )
For some reason, all my dwellers lost "happiness" from a global of 80% to 10% in about 2 hours.
All my resources tumbled to near zero ( all in the red zone)
All my dwellers are sick and irradiated.
The only thing that I can see as the cause of that is that there was a raider invasion that resulted in 2 dead (and revived).
I am not certain of the game mechanics when there is a failure like that.
Any hints ?
Thanks.

This happened to me when I left the game mid-raider attack. I wasn't able to log back in for a few hours and when I did, the same thing happened (loss of people/resources/happiness).
I have not read any 'official' comments regarding this, but leaving the game during any event causes the dwellers not to respond properly.
