Hello Subnauts,

Our second hotfix for the Subnautica 2 Buddy System update is out now!

We’ve fixed several issues and bugs, including Voice Chat detection, the Tadpole being incorrectly teleported, and the Scanner Station’s resource accuracy.

The full list of changes in today’s hotfix is below.

  • Fixed Biobeds displaying the incorrect mesh after being moved and the game was reloaded.
  • Fixed Tadpole being unable to dock in certain orientations when their own vehicle geometry blocked the docking check.

  • Fixed Tadpole being incorrectly teleported when returning from out-of-bounds areas.
  • Fixed destroyed Tadpole with attached chassis modules failing to teleport back into bounds correctly.

  • Fixed an Xbox memory leak related to audio commands accumulating while the game was paused or constrained.
  • Updated the game's crash reporting system to improve crash diagnostics and stack trace collection.
  • Re-enabled crash reporting and crash-on-launch logging after resolving issues that could cause hangs.
  • Updated supporting crash reporting components across supported platforms.

A reminder: If you play Subnautica 2 with mods, please temporarily disable, remove, or uninstall them before launching the game following the hotfix. Community mods will not be updated for compatibility with the latest hotfix, and may cause crashes or other unexpected behavior on launch. Once the mod creators have updated their content, you can re-enable and reinstall your mods. 

This hotfix may take some time to roll out worldwide.
