[June 7, 2026] - Submarine Occlusion & Suffocation Fixes

Bug Fixes

• Airtight Submarine Suffocation: Fixed a critical bug where players would suffocate and lose bubbles while safely inside an airtight submarine. NeoForge's custom fluid type checks (getEyeInFluidType) now correctly recognize the submarine's interior as empty, eliminating server/client desyncs and ghost bubbles.
• Corner & Walking Occlusion Glitches: Replaced the grid-based position checking with exact decimal (Vec3) local-space physics. The water occlusion tolerance has been expanded to include the physical boundaries of the hull itself (VISUAL_UNION). Players will no longer start drowning when walking on the floor, getting pushed into walls, or standing in tight corners of a heavily pitched submarine.
• Swimming Prevention: The game will now forcefully prevent players from entering swimming mode while inside the submarine's occluded area.
