Game went down, when restarted horse and saddle gone

I was playing Saturday night or technically Sunday morning at about 2:00 am mountain time usa, and my minecraft just blanked out from what I think was an update. I say that because the rest of my computer was fine and operating normally and one previous time when minecraft went down like that when I pulled it back up the settings screen had changed. But I was riding on a horse I had just tamed out in the wild when minecraft went down and when I got the game pulled back up I was in a bit different location and the horse and Saddle were gone. I've looked all over the area and not to be found. What the heck is up? Thanks.
