My horses keep disappearing while I am not playing. I've tied them to leads, put them in a pen, and done both at the same time, but they still disappear. I live on a very small island so they couldn't have wandered off. When they disappear while on a lead, it still shows the lead on the fence, but there's no horse attached to it. I save and quit when I get out, so it's not still running while I'm out. The most frustrating part is that it has only happened to the horses that I have tamed. When my friends get in the world and take horses theirs don't disappear. I don't know what to do. I've tried everything. I just want a horse.
