I have two rooms that my dwellers happiness drops all the way down in no matter what I do.

I have looked for the body there isn't one

I have checked my gear list all my dwellers are living.

I have closed and rebooted the app

Nothing works! How do I fix this problem?

I had to delet the two fully upgraded 3 wide rooms and re make them

Very upset that was time and caps down the drain I find myself not wanting to play anymore it will just happen again! Not a recommended game at this point. If the bug gets fixed it would be a great game. At the least I would like my caps back. Or rewards for sticking with the game at least, it's no fun for the players.

This is already reported bro, we all waiting for update. I don't have such problems and crashes but still I'm sad that many players lost vaults and other all stuff.
