I had some levels of water that I was letting drain by gravity. After awhile the water was on the floor, but very shallow. When I set the microbe musher to make lice loaf, the dupes kept getting 1 kg at a time from the water and delivering it to the musher. Like all of them for a very long time. I think they should try to grab more water from the next tiles before heading back to drop off.
In my first colony, I set the temperature units in the options to Fahrenheit. This worked as expected. Upon creating a second colony, the temperature was displayed in Celcius, even though the settings showed Fahrenheit was still selected. To fix issue, I had to set units to C, close settings, open settings, set to F.
