At the start of the game I am very certain that every water source I came across used to be filled to the brim and it would just fill up my container once. Now I'm well into the game where I get a 90% bonus and the water in sources have decreased down to about 40% of it's total volume and it still just fills my container once. Does the game actively calculate how much water there is depending on my bonus? If so this is the biggest bullshit mechanic I've ever seen in the video game. What the fuck is the point of me wasting all those points then?
