an invisible ground at height 257 is created, which makes it impossible for the player to climb to that height and to descend if he is on a mountain.

this ground appeared when I was teleporting to the sky until I teleported to +200 blocks upwards I was falling and I arrived on this invisible ground that even at a high height I did not take fall damage and the same thing happened below this ground, there was a ceiling that wouldn't let me go above the height 254
