the game crashed while i am riding my hourse with my xbox account logged in and after i get back in he is gone

I was riding my horse and ready for my adventure for exploring my map's undiscovered areas with my xbox account logged in. Suddenly the game crashed and i am at the main screen, and when i am back in, the horse is gone with my diamond horse armor ;-; 

I was forced log into the xbox account without internet connection, idk if that affects this or not, since i experienced once before like a year ago and i was connected to the internet...
