Happiness of 2 dwellers in the vault door was found lowered yesterday and became 20% this morning. Checked the dialogue and found "working with a dead body", but the dead wasn't there. This is a dormant vault and I do not recall and casualties lately. Before that, just completed an objective of surviving death claws attack, so there would be no one dead. However, two guards at the vault door were found missing afterwards.

The game took away 2 of my best dwellers with best gear and I cannot guard the door.

I do not want to delete this vault with 182 full stat full level dwellers and lots of legendaries.

This game really drive me crazy:(

There is an existing thread about this issue... Simple solution if you bothered to search before posting... Move the dwellers out of the room, delete the room, rebuild the room an repopulate it.... It's not rocket science.

Mine is the Vault Door, that can never be deleted.

I have this same problem with one of my dwellers. They've disappeared along with the dog that was equipped to them and as you say you can't delete the vault room. svcks.

Sethvir's attitude and literacy skills also svck.

I am having the same problem also, it is the Vault so deleting the room doesn't work for me either. No dead dwellers on my list either.....

Apparently this is still an issue. Even the people in the rooms next to the vault door start slipping in happiness. I tried waiting a couple days then assigned someone there and his happiness went down like a countdown while he was running up the five levels to get there.

Ive noticed my 2 door protectors are 15% happy and looking at their chats a dead body is always in there but no trace at all, and ive lost about 10 full stat dwellers too into thin air, but luckly their outfits and wepons go into my inventory
