Minecraft 1.21 testing

The latest version of Minecraft is being test by Supreme Leader, unlike the last time she tested the latest version, the version she downloaded seems to be stable and has a high potential to pass her expectations. Her colleagues suggested to test Gibonz's Polar Express addon, but the latter denied as she eant to make sure MCA Train Addons will work properly first. Then she will reconsider testing any of Gibonz's addon.
