Game crashes when attempting to ride a horse

Note: this also happened on my Kindle Fire HD while joining the world that was on my iPhone 6s. When I hit “Ride,” my game crashes. The thing is, it didn’t start right away. I had tamed, saddled, and even horse armored the horse (the ladder may or may not have been cheated) and rode it a bit. Then I joined with it on my Fire HD8 tablet and ride the horse. After a bit, it crashes whenever I joined on that device (only on that device, my phone, where the world was, was fine) it only crashes the client. Unless the host is riding it. Now it always crashes when I try to ride that horse. I should add that I think this started when I did effect @e health boost and regen so those could be related. Actually, I just /effect @e clear-ed and tried to ride the horse again. It still crashes. They still could be related, as I think it started with that.
