I was had ridden my horse into a river and when it started to go under, as usual, I was kicked off of it, but when I was kicked off the horse disappeared. There were bubbles and splashing noises made by the horse (I know it was the horse because I was out of the water and there was nothing else around) and I tried to click there to see if it would let me get back on it, but it didn't. I went to bed and woke up and the splashing noises and bubbles were gone. I looked around for the horse but there was no sign of it. This is the second time I've ridden a horse into water and it disappear once I was kicked off of it.
