Phantom Chunks Glitch (Edge of Map)

Phantom chunks that usually render beyond the 30,000,000 mark do not generate. The world just ends suddenly, appearing to drop straight off into the void. The wall that usually prevents travel beyond 30,000,000 is also bugged, when colliding with it the player gets stuck and cannot escape. When non-player entities collide with the wall, they disappear as if they have despawned/teleported.
