What's the issue? Please include any error messages you receive and as much detail as possible.
I came back to lioden after taking a long break. When I went to sign in again, the game made me re name my king, who was the same as the one I had before I took a break, and now he's showing up on all records as deceased despite being alive and having the same age as when I left the game.
When I click on the list of cubs he has sired, none come up despite having sired 19 cubs. He still has his heritage, all markings, stats and even decor as he had before I took a break, but all his cubs and records of him existing previously to my breaks are gone.

I took a break for a couple of years, came back, logged in, the site made me change my main lion's name as if I were opening a new account, my pride and main male appearance are all the same, but he is missing from all his cubs records, and all the cubs he has sired are missing from his info despite having sired 19.
