Sunkenland Update v0.8.80 Reduces Stutter and Speeds Up Shark Achievement Progress
The patch also fixes multiplayer Chain Explosion progression, fishing UI lockouts, boat position switching, and aquarium geometry.

Sunkenland Update v0.8.80 focuses on performance and save-loading improvements, with scene management changes intended to reduce memory use and raise frame rates. Players with heavily wired bases should also see less stuttering when loading saves, while shorter shark respawn times make related achievements easier to complete.
Several multiplayer and interface problems are addressed as well. The patch fixes Chain Explosion achievement progression for clients, restores the UI after fishing, and makes it more reliable to switch between operating positions on a boat. Vector3 Studio details the changes in its official Steam announcement.
The update follows Sunkenland Update v0.8.55, which focused on multiplayer stability, ship combat, crafting, construction, and save recovery.
