In Creative Mode, after cramming a truckload of Piglins in the Nether in the same block (don’t ask why), they started to clip out of their cage diagonally in all four directions. They didn’t interact with the terrain, but you could hit them, causing them to snap back to their original spot. I decided to add more to see what happened. They began to glitch out farther than before, so I followed them. They disappeared suddenly along with the rest of the other Piglins when I got farther out. When I returned to the cage, it was very laggy. Projectiles fell slowly. Pistons updated the pushed blocks very late. And worst of all, the lag still persists to this very day, even on different worlds. Unfortunately, I didn’t capture footage of the event and I’m too scared to try it again, out of fear of corrupting all my worlds. Hopefully this gets fixed soon.
