Unknown Worlds has released a second Buddy System hot fix for Subnautica 2. We have highlighted the most important fixes and changes.
Creature & Vehicle Interactions
- Leviathan & Tadpole Tweaks: Improved the Leviathan grab attack on the Tadpole sub. Additionally, the Shiver Leviathan will no longer attack or interact with unpiloted vehicles.
- Tadpole Out-of-Bounds & Docking Fixes: Fixed docking issues caused by vehicle geometry blocking checks, as well as bugs that caused the Tadpole or destroyed chassis modules to fail to teleport back into bounds correctly after going out of bounds.
Base Building, Power & Equipment
- Power Generation Fixes: Resolved bugs causing Thermal and Hydroelectric Generators/Turbines to display incorrect power output or lose power entirely after being streamed out of the world and back in.
- Scanning & UI Fixes: Fixed accuracy issues with the Scanner Station when locating resources. Also enlarged the scanning hitbox for the Advance Battery and fixed missing scan data/UI icons for habitat display cases and Bloom Biofilm.
- Biobed Visual Bug: Fixed Biobeds showing the wrong mesh after being relocated and reloaded.
Voice Chat, Graphics & System Stability
- Voice Chat Consistency: Improved voice activity detection to treat local and remote players uniformly.
- DLSS / VSync Behavior: VSync is now automatically forced off when enabling DLSS Dynamic Frame Generation to prevent display conflicts.
- Xbox Memory Leak: Patched a memory leak on Xbox hardware caused by audio commands piling up while the game was paused or constrained.
- Crash Reporting: Restored and updated the crash reporting systems to collect better diagnostic data on crashes and launch hangs.
Important Reminder for Readers
Mod Compatibility Warning: The developers urge players using mods to temporarily disable or remove them before running the game, as existing mods are not updated for this hotfix and may cause launch crashes.
