See title. The tile in which the water should be once it exits the liq. vent is just the gas that was around there. I've done this in an attempt to make a water lock that is more like a stair case. The water pit is 1 by 2 tiles.
Steps to Reproduce
Make a stair case water lock such that the pit is 1 tile long and 2 tiles high. Place a liq vent on the upper tile of the pit. Move water via the liq. pump using a liq. valve set to any value less than 1.
