A couple of days ago I was playing Fallout Shelter for the first time in a few days (the game wouldn't open up my 55-ish person vault at all until the latest update), when a molerat rush killed about 5/6ths of my vault dwellers. I've resurrected them all at this point, but in one of my dining rooms the dwellers are still complaining about a corpse, despite the fact that there is no actual corpse there. Since their 20% Happiness rating is hurting my overall happiness, does anyone know how to fix or get around this glitch?

demolish and rebuild the room would be my suggestion :/

Darn. It's in the middle of other rooms, and they're all fully upgraded. I guess I could just leave the room mostly empty, except for one miserable person who would keep an eye out for more molerats. Maybe Bethesda will fix it in the next update.

Same problem in my three part fully upgraded power room. No clues yet how to fix it without demolishing and starting all over.
