When on horseback mostly (though sometimes not on horseback) there is an invisible barrier that stops forward motion

The invisible wall also stops projectiles. If a mob is on the other side of the wall, then the arrows will suspend in the wall. Similarly, when I shoot arrows they are blocked by the wall. The invisible wall prevents mobs from moving as well. If I engage in melee with a mob on the other side of the wall then the mob stays “red.” I can shear a sheep on the other side of the wall, but cannot gather the wool. When playing multiplayer, the “invisible wall” appears for specific users (player 1 can’t pass the wall, player 2 and 3 are unaffected).
