Liquid duplication when falling and pressing another liquid simutaneously

Well that certainly is easier to debug, thank you. The logic for displacing a neighboring tile of a smaller amount of liquid is using the mass of the tile in the previous frame and failing to notice that update liquids has already committed the same mass to falling into the cell below during the same tick.

Satisfied to see the bug fixed, and here's a similar situation while two cells of the same liquid are falling during the same tick:

In that case, the mass above is converted to 1/8 of the mass below. The save file is uploaded for reproduction.
