A few days ago I was playing in my Hardcore world, on that day while exploring nether I found a bastion and decided to assault it, after being there for a while an Invisible piglin began to attack me, it was not only invisible, but also could not hit it nor could I put blocks where he was, I tried to climb (he had thrown me into the lava) and the piglin being invisible simply did not allow me, he stressed, he was not only invisible, but also could not, it's as if he were now and not at the same time, like someone being in creative mode with invisibility. For it, I died.
