I was playing and I had my horse just disappear.

I was rideing my house, my game mode was peaceful. I found a villige I went over and my horse fell in a hole in the water. It was under a block. I went to save it as so as I could. It just disapered.It didnt die or drop anything. Just disapered It was wearing a saddle and golden armor. So sorry. The hours actually teleported across the map about 100 blocks.
