[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.
