I have a horse stable in my realm and for some reason, my horses keep disappearing. All the horses have been tamed and are wearing armor and a saddle. I have checked the area to make sure there's no way for them to escape on their own. This has been happening for some time now. Even my favorite horse that had a name tag along with all its gear disappeared overnight along with my donkey and my mule. In total, I have lost 15 horses due to this 'glitch' or whatever keeps happening that is making my horses continuously disappear.
