Inside my Vault I had a large raider at I that really cut away at my population, fortunately I had enough money to revive them. But now my dwellers are complaining about corpses when there are none. I have 32 dwellers and all are alive and well. Is anyone else experiencing this issue or is it just me?

Yeah, that has been a problem for me. I think that I removed a body from that room. The body was removed, but the people in the room still complained like you said. In the end I had to destroy the room and rebuild it at great expense.

Also experienced this in two different rooms. One,i moved the dwellers out to the living room made the hapiness to 75 and went back. It was fine. So. Two, thought it would work on the second room as well. Did the exact same thing. It was fully upgraded 3 width training room. I destroyed the place and rebuilt them. Unless bethesda is planing to use the ghost concept it seems like a bug for sure.
