¶ 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.
