One of my best dwellers (rare from e lunchbox) got to level 56. It was not a natural leveling. The last time I recalled this dwellers from the wasteland he was level 46, and I put him in the classroom (where as far as I know, they don't gain experience), with a legendary cat for faster learning, ever since. Today when I checked the dweller because I wanted to send him in the wasteland I noticed that his level is 56. I sent him in the wasteland anyway and the game crushed (for the first time, it never happened before). And I was unable to login in this vault after that, the game just freezes when I try to. I deleted Fallout Shelter, then downloaded and installed it again. When I recovered the vault from the cloud, it was working well again, but this dweller is still level 56. Now I know I can just NOT send him to the wasteland or evict him to be even more secure, but this is an obvious bug and it can happen again if I don't know what triggers it.Has anyone encountered this bug/glitch and knows what I can do to fix the level on this dwellers or at least avoid future situations like this with other dwellers?
