Tamed and named horses disappear from stables

I have had multiple horses, all tamed, disappear from my stable. There was no way for them to escape or get hurt. One was only tamed, one was tamed with a saddle (the saddle disappeared as well), and one was tamed and named. There has also been a llama with carpet on it that disappeared. The stable is all within one chunk that I never leave. One of them disappeared after the game crashed, but the others disappeared randomly. If I am doing something wrong please let me know, I would greatly appreciate it. I saw another issue like this, but it said it was resolved so I figured I need to make my own. Thank you very much!
