I was playing survival with my friends on the new snapshots and when i entered the end, i started digging up, it was taking a LOT of time to get to the top so we just went spectator mode, and guess what? the island went up to Y=190, all the pillars were covered in endstone, we didnt even have to break the crystals. the same happened to the end cities, they went up to 255. the end looks very cool like this but its not playable.
