Tamed, names, saddled and armored horses disappearing.

There have now been several instances where tames, names armored and saddled horses are disappearing. I have lost 7 horses now. All happened after the 1.16.2 came out. I have for years stabled my hours in the same location for and never lost a hours. I always leash them before logging off. In all instances the horses are no longer there when logging back in. I have lost 4 diamond horse armor, 2 gold and 1 iron. Which is bad because its not easy to find.
