As I was playing realms (10 person), my friend told me he was stuck and glitched on his horse. Every time he got about 10 blocks away from it, he would get teleported back to the horse. The horse was not visible when within around 6 blocks as it would disappear. This did not stop the bug from occurring. The horse did not take any damage and my friend kept teleporting back to it and crashing. He kept on leaving the realm and rejoining, but did not fix the problem. After we BOTH left the game, the bug had fixed. Please fix this bug as we don't want this to happen again. Thank you!
