Angry Piglins (not zombie piglins) are able to walk threw open trapdoors if they are one of the walls of a 1 by 1 hole (1 block space with X height) even though they should just fall down the hole, I found this out while using my gold farm while afk, and lets just say I had a surprise when I woke up the next morning. Please fix this soon!
