If you enjoy playing Vanilla Minecraft, but also enjoy Modded Minecraft, how can you play both on one server? Surely your progress would be lost when switching, right? Wrong! With every Stickypiston Server, you get four server instances on one control panel! Install the latest Vanilla Minecraft release on one instance, install your favourite Modpack on another, and switch between them with ease! Anything you do on instance won't be affected by your other instances. Everything is saved!
