Dupes will bring 1 kilo of algae to an algae deoxidizer which will IMMEDIATELY be used down to about 80g. This creates an infinite loop of the dupes using all available algae to never fill the machine. I've also seen this bug with plants where no matter how many times they brought water, the plant always said it was low on water. They drained an entire lake to never grow a mealwood plant. As I typed this, I saw the same thing with an algae terrarium. bringing infinite water and algae to it. *edit* I did notice it's when it says they deliver "1000g" of material instead of an amount of kg. Is the bug only when they pick up and attempt to deliver under 1kg?
