Bug: When batch crafting half of the liquid ingredients may be lost?

I’ve seen this a few times, haven’t narrowed down exactly what is happening, but basically I go to craft something with (it says) all the ingredients necessary but then it says actually I need more ____. It looks like if the recipe says 2 salt water then it actually takes 3. Note that I’m not getting the “You mess up and lose X% progress” message. Here I’m trying to craft two antiseptic powder.
