So here's a pickle. One vault guard, we'll call him Chipper, is perfectly happy in the vault entrance -- "I'm so happy I could pinch myself." The other vault guard, we'll call him Grumpy, is supremely unhappy in the vault entrance -- "Oh, a corpse! Isn't that pleasant."
Problem one is, there isn't a corpse anywhere in the vault.
Problem two is, every dweller I swap in for Grumpy also complains about a corpse.
Problem three is, the vault entrance is already fully upgraded so no clearing the glitch that way.
Do I just tell Grumpy, "svck it up, buttercup?"
