This update is
exclusively for performance improvements.
What this update improves upon, is that placed Shulker Boxes won't tick in unloaded chunks unnecessarily, this improves performance by a huge margin, while the inventory of each Shulker Box is saved correctly.
If you haven't done so already, please update to the latest version, as new updates introduce new features, performance improvements and most importantly, bug fixes.
If you are having issues with the latest version, please reply to this resource page and let me know what the issue is and I will try to resolve it as fast as I can. Or alternatively, join our Discord and ask for help there.
