I had several horses inside of a stable with my donkey and then when I went out to a far away abandoned village and came back 4 horses and their armor and saddles where all gone. A friend mentioned that this is a known bug and told me to exit my world and come back, and I did that I even turned my device completely off then restarted it and still no horses. This is really upsetting as I worked hard in acquiring 4 saddles and 2 iron and 1 diamond horse's armor.
