Isn't there many ways to dupe on 1.8.x, 1.9.x, 1.10.x, 1.11.x, 1.12.x? You just don't know them all. There will ALWAYS be a way to exploit ANY game in some way. It is just logical to add support to the new updates as many people just hit play and don't know if their launcher is set to automatically play on the latest update. Also it is annoying to change versions every time I want to play on this server or any other that supports (or not) 1.12.1+
Going to move to the archives, seeing that we are up to 1.12.2 support . https://www.mineverse.com/threads/1-12-2-support.134233/
