I have a Vault that had 5 Mr. Handys. A couple days ago I noticed that they had all disappeared.

I recently deleted another Vault that also had 5 Mr. Handys. I'm wondering if that didn't also delete the Mr. Handys from my existing Vault?

The Mr. Handy boxes also disappeared from my Storage rooms, so for some reason the game decided to eliminate all traces of them.

Has this happened to anyone else?
