There are very strong dupes through animals (Alex's Mobs) and vanilla animals, and there are also dupes through the Supplementaries mod through bags, where a bag falls into a portal in Ender and is teleported there and duped, thereby prohibiting the passage of objects / falling blocks / animals into the portals We fix a bunch of bugs and dupes at once. I would like to see this function in quark, where it would also be possible to specify a white list of objects and animals at the entrance to portals
