The changelog also reduces attack stuttering, fixes quest and achievement issues, and corrects aquarium capacity behavior.
Sunkenland Hotfix v0.8.86 addresses several problems that can disrupt multiplayer sessions, especially when enemies or boats are involved.

The announcement published Sept. 18, 2026, also covers quest cleanup, achievement progress, settings issues, boat collisions, disembarking, and Aquarium behavior. The full details appear in the official Steam announcement.
