1.21.8 Update

The 1.21.8 Update is a minor update whose main feature is the move to the 1.21.8 version of Minecraft, along with a few minor bugfixes and changes.

It was released on the 18th of November 2025.

Changes

• Updated MRCL Recommended Modpack to 1.21.8.
• Most items found on Earth will no longer be able to be stacked.
• Consuming food from the cafeteria will now restore health.
• Mirrors will now be able to reflect 10 lightning bolts from Possessed players instead of only 1.
• Players will now have to hold right-click while holding food trays or mirrors to defend themselves from lightning bolts.
• Earth now contains a few new biomes to allow for more customizability with Music Packs:
  • Laboratory
  • Scanners Room
  • Supercomputer Room
• Some more flora has been added to certain seasons on Earth.
• Tessens now have a different charging animation and will launch automatically once fully charged.
• New Creativity structures have been added in the Volcano Replika and the Shell Sector.
• The Desert Sector icon has been updated using a reference from the show.
• The Sector 5 player step sounds should now be consistent.
• The Sector 5 maze keys will now instantly stop the timer when hit instead of when the animation ends.
• XANA Towers activated by xanafied players will no longer automatically deactivate by themselves.
• The player skin portion of devirtualization animations will no longer be emissive (meaning it will not be abnormally bright in dark locations.)
• Communication Cards of players that trust you will open automatically when they virtualize while you are sitting at the interface.
• The Monster markers on the Virtual Map are now more stable.
• Overvehicle markers have been added to the Virtual Map.
• Terminals will remember the position of windows that have been closed, allowing them to be re-opened in the same spot until they are shut down.
• The Virtual Menu has been heavily modified, no longer having a background due to technical issues caused by Minecraft and several sub-menus now using the vanilla game's "dialog" system.
• Added two easter eggs.
