[1.21.4] Space Update 1.0

Important note for servers: You will need to also add luminance-1.0.0-alpha.5+1.21.4-fabric-server.jar to your server mods folder, clients won't need to do this.

By request of the Modrinth Moderator Team - due to section 5.7 of Modrinth's Content Rules, luminance-1.0.0-alpha.5+1.21.4-fabric-server.jar was removed as a additional file, it's still avaliable on Github for those who need it. This only effects servers, clients do not need to download this.

Developer's Note

We took the "Steve Co. Supply Crates" (also known as "Locked Chests") from Minecraft Beta 1.4,
and made them link to the actual minecraft shop. See here for more info on the original!
This mod contains a reference to "Supply Crates" (a.k.a. "Loot Boxes", "Crates", "Gambling"), which we do not support, nor do we endorse the use of these for exchange of real-world currency. These are predatory practices designed to cause harm, and we encourage you to avoid them.
This reference was intended to make fun of companies that use these predatory practices.
