there are 2 Bugs: 1: a bug that when you ride a horse and fall with it in water (it can also happen on land) and you get back on it, it teleports you to the last place you fell 2:If there is a chest next to a bed over time or leave and return to the location, the bed will become invisible but it will be there.
