The 1.1 Adaptive Measures update delivered over 120 bug fixes, with crash resolution as the top priority. The most impactful fix addressed a memory leak that caused crashes during extended play sessions, particularly when transitioning between many biomes. Players who experienced crashes after two to three hours of play should see dramatically improved stability. The leak was traced to creature asset loading that failed to release memory when biomes were unloaded, and the fix implements proper asset garbage collection on biome transitions.
A second major crash fix targeted save corruption during base flooding events. Previously, if a base flooded while the game was saving, the save file could become corrupted and unplayable. The fix implements atomic save writes, meaning the save file is only updated if the entire write completes successfully, preventing partial corruption. This is a critical fix for players who lost hours of progress to save corruption. Additionally, crashes triggered by rapidly building and destroying base pieces in co-op were resolved by improving network state synchronization.
Several smaller crash fixes addressed edge cases: crashes when scanning certain fauna in specific biomes, crashes when entering vehicles with full inventory, and crashes when the Scanner Room attempted to track creatures in unloaded chunks. While these were less common, they were frustrating because they occurred unpredictably. The 1.1 patch's comprehensive approach to crash fixing has made the game substantially more stable, and most players report significantly fewer crashes than at launch.

Performance and Optimization Improvements
Performance optimization was a major focus of 1.1, with measurable improvements across demanding biomes. The Deep Lilypad Caves, one of the most performance-intensive areas due to dense bioluminescent flora and particle effects, saw an estimated 20 percent frame rate improvement on mid-range hardware. This was achieved through optimized particle rendering and improved culling of off-screen light sources. Players who experienced stuttering in this biome should notice smoother traversal.
The update also improved loading times when transitioning between biomes, reducing the stutter that occurred as new terrain and assets loaded. This was accomplished through better asset streaming and preloading of adjacent biome data. The improvement is most noticeable when traveling at high speed in a vehicle, where biome transitions happen rapidly. Additionally, CPU usage during base building was reduced, making the Habitat Builder interface more responsive in large bases with many placed pieces.
For lower-end hardware, 1.1 added new graphics quality presets that let players trade visual fidelity for performance more granularly. The new Low preset disables volumetric lighting and reduces particle density, providing a playable frame rate on hardware that previously struggled. The Medium preset balances visuals and performance for mid-range machines. These options make the game accessible to a wider range of hardware, addressing complaints that the launch build was too demanding for modest systems. Players should experiment with presets to find the best balance for their setup.
| Area | Improvement | Impact |
|---|---|---|
| Deep Lilypad Caves | 20% FPS gain | High |
| Biome loading | Reduced stutter | High |
| Base building CPU | Lower usage | Moderate |
| Graphics presets | New Low/Medium options | Moderate |
Gameplay and Physics Bug Fixes
Beyond crashes and performance, 1.1 addressed numerous gameplay and physics bugs that affected the play experience. The most notorious was the vehicle fall-through-floor bug, where the Tadpole and other vehicles could clip through the seafloor in certain biomes, becoming trapped underground. This was caused by a collision detection issue with specific terrain meshes and has been resolved by improving collision geometry validation. Players who lost vehicles to this bug can recover them by loading a save from before the incident.
Creature behavior bugs were also addressed. A bug where Bonesharks would become stuck in a circular patrol and never break aggro was fixed, restoring their intended pursuit-and-disengage behavior. A bug where the Chelicerate's grab attack could damage players through vehicle hulls was resolved, preventing unfair deaths. The Cryptosuchus charge timing was adjusted to be more consistent, eliminating the bug where its lunge animation would sometimes skip, giving players no reaction window. These creature fixes make predator encounters more fair and predictable.
Base building bugs received attention too. A bug where hull integrity was calculated incorrectly after removing and replacing pieces was fixed, ensuring that integrity values update accurately. A bug where bulkheads failed to seal during flooding in certain room configurations was resolved. The Reinforced Window, new in 1.1, had a bug where it provided less integrity than intended; this was corrected in a hotfix shortly after release. Together, these fixes make base building more reliable and predictable, reducing the frustration of unexpected floods or collapses caused by calculation errors.
Known Remaining Issues and Workarounds
Despite the extensive fixes, some known issues remain after 1.1. The most significant is an occasional biomod effect failure after save reload, where tier-three biomods, particularly Symbiotic Gills, stop applying their effects until the player re-equips them at a Biomod Station. This was hotfixed within a week of release, but some players still report it intermittently. The workaround is to visit a Biomod Station and swap the affected biomod out and back in, which re-applies the effect.
In co-op, desync issues persist in specific scenarios, particularly when multiple players build simultaneously or when a player joins mid-exploration in a complex biome. The 1.2 update promises to address these more thoroughly, but for now, the workaround is to have the desynced player leave and rejoin the session. Another known issue is audio cutting out in biomes with many simultaneous sound sources, which the team is investigating. Restarting the game temporarily resolves audio issues.
A minor but annoying issue is that beacons occasionally disappear after a save reload, particularly custom-placed beacons in deep biomes. The workaround is to re-place the beacon, though this is frustrating if you do not remember the exact location. The team has acknowledged this bug and plans a fix in 1.2. For players affected by any remaining issue, the official bug tracker is the best place to report problems, as the team actively monitors it and prioritizes fixes based on frequency and severity. The overall trajectory is positive, with each update measurably reducing the bug count and improving stability.
Players should always back up their saves regularly, especially before major updates, as a precaution against any unforeseen save issues. The 1.1 update was save-compatible, but backing up is cheap insurance for the dozens of hours invested in a playthrough.
