I have been playing a realm with my friends a lot, i decided that I would want to make a mob museum and a shulker box farm. Both of these would require a shulker and i wanted to make the shulker box farm in the overworld so i went to a end city, got the shulkers to the end portal, and was proud of my self. I then sent the shulkers through the portal and i was exited to find them at spawn. Nothing was there. I searched and searched and find an answer as to why they were gone and i saw a post that said the same thing that happened to me and it said that mobs that are transported from the end to overworld spawn at y 512+ but almost nobody talks about that post anymore. There wasn’t a solution to it either. I used my elytra and flew straight up at spawn and i found the shulker floating at y level 512. I have no way of getting it down because it is past the build limit. I could make a tnt launcher that launches a minecart and catches the shulker but i do not know to make one and i cant find a tutorial for a tnt minecart launcher either. If this bug doesn’t get fixed, could someone please guide me through building a tnt launcher that launches a minecart, and the minecart would then get launched into the air, catch the shulker, land on rails, and not take any fall damage. Thank you for reading this and helping me if you do.
