My horse disappeared when I changed my skin

My skin was back to normal.
So I wanted to change my skin.

Entretemps j’ai du mettre en veille ma nintendo switch, quand je suis revenu j’avais été déconnecté.

I took advantage of having to reconnect to change my skin.
When I came back to the Realm my horse had disappeared. It was named, a diamond armor and a saddle.
I went around the map to find him, but I couldn't find him.
