- Fixed particles going through closed gaps (e.g. closed doors).
- Gaps can emit particles even if the target hull is full of water (-> water running into the sub through an already flooded room is more apparent).
- The air-only splash & waterdrop particles are not emitted if the target room is full of water.
- Fixed heavy water particles never moving upwards (even if the water is rushing into a room from a gap on the floor).
