For some unknown reason, it is possible to end up with fractional amounts of countable foods and ingredients (here: 2.3 peppernuts; I've seen this with other foods as well). Once this happens, any supply and storage tasks involving these foods will be performed in very small amounts (999.5mg of Omelette, "0" (actually, 0.001) Hatchling egg, ...). Dupes performing these tasks are rendered effectively useless, spending several cycles to move a single meal from the grill to the fridge. Reloading sometimes mitigates the effects for a short period of time, but so far they have always returned for me.
(side note: the macOS save file location is ~/Library/Application Support/unity.Klei.Oxygen Not Included/save_files, at least on 10.13.3.)
Steps to Reproduce
Unclear. Play for a while? Sorry. :/
