My dwellers are in the kitchen on 10% happiness due to them detecting a dead body in the room when in fact there is no dead body there. That is the room the invincible mole rat from the storage killed everyone I sent at it (30 people dead, around 500 caps each I spent to revive). I get bad reports and failures when rushing; I usually do not complain about game difficulty but these are obvious bugs and I truly believe a refund of my caps and a bug fix is the least Bethesda can do; I had 6 people with rifles 5+ on damage (1 had 12 on attack) and they all died... luckily I had some kids (around 4) and I did not log back in until my guy came back from wasteland and kids were grown to run the most basic survival needs. Contacted support and they sent me here to seek help...

There are many other threads discussing about this bug

Only way to fix the bug is to remove the selected area where the 'dwellers are detecting dead bodies that aren't there'
