My allay disappered of my house and my diamonds

I play minecraft in my cellphone and with my close friends have a realms and we played every free time that we have but we have noticed that this version has many errors o bugs since you fall by putting blocks up, see the transparent floor when you connect to the game until mods or items disappear, yesterday i lost my alley and my diamonds of my chest, I asked my friends but no one had played because of their jobs, my ALLEY was in my house and i had it tied up with a rope when i entered the game i went from the mine to my house and it was gone, this type of things hinder my experience in the game because you lose the desire to play
