## [June 17, 2026] - Performance & Dedicated Server Fixes ### Bug Fixes & Refactoring - **Dedicated Server Crash:** Fixed a critical issue preventing dedicated servers from starting due to `FlowingFluidMixin` and client-side code stripping. - **Decompression Chamber Performance:** Massively improved the decompression chamber's TPS performance during filling and draining by optimizing the compartment BFS (Breadth-First Search) to only run once per tick instead of for every block filled. - **Fluid Duplication Fix:** Fixed a bug in the decompression chamber's fluid handlers that would incorrectly duplicate or void fluids by scaling transfer rates artificially. The block now correctly respects the 1:1 fluid mechanics. - **Waterlogged Block Protection:** The decompression chamber will no longer accidentally destroy and replace waterlogged blocks (like slabs and stairs) when attempting to manage water levels inside the compartment. - **Coordinate Mapping Accuracy:** Fixed a severe bug in `EntityWaterPhysicsMixin` where player coordinates were incorrectly calculated in global world space instead of local sublevel space, breaking airtight submarine suffocation/swimming checks. - **Memory Leak Prevention:** Patched a static memory leak in the decompression chamber that prevented unloaded or destroyed chamber water blocks from being garbage collected.
