Sunkenland v0.8.53 Patch Notes Cover Quest Bugs and a Weaker Final Turret
The changelog also corrects interaction prompts, a respawning treasure chest, and ladder and collision problems at the Nuclear Power Plant.

Sunkenland v0.8.53 is a focused patch that addresses several quest progression problems, interaction prompt errors, and traversal issues. The latest Steam announcement also details a major health reduction for the final boss turret.
The Pirate Cargo Ship quest could sometimes fail to show Objectives 2 and 3, blocking progress. The Tunnel quest also had a treasure chest that could return after reloading a save, even if it had already been collected. Elsewhere, the patch corrects incorrectly displayed interaction prompts and fixes ladder and collision problems in the central area of the Nuclear Power Plant.
For the final boss encounter, the turret’s base health has been reduced from 28,000 to 14,000. The difficulty multipliers remain unchanged, so the turret still uses different health values based on the selected difficulty.
v0.8.53 follows the Aug. 16 v0.8.52 hotfix, which addressed an error that could prevent a world from loading correctly.
