I set up 4 "experiment cells" with the following properties:
- Lamp (Rowan)
- Lamp + Mess Table (Nails)
- Mess Table (Nikola)
- Empty Control Cell (Jean)
Using sandbox mode, I spawned in the above duplicants, and they all had identical calorie counts. Since they were in a small, climate-controlled room, there is nothing to spend excess calories on, and so they should remain at the same calorie count if they are fed the same items.
Each duplicant was given a single Mushbar (again, sandbox mode spawned), which should have added an equivalent 800 calories. And yet, now you see how the light has done it's evil work -- Nails and Rowan both are hungrier than their peers. (With Nails having sacrificed an additional 10 kcal to feed the dining table - something the canny Nikola avoided due to not using his dining table (despite it being assigned -- an unrelated bug, presumably).
Steps to Reproduce
Have two duplicants with identical calorie counts begin consuming food. Have one of the duplicants be in a lit tile (receiving the "Lit Workplace" buff) Serve the duplicants an equivalent amount of kCals Note that, after eating, the kCal delta between the two duplicants is different. Mess halls also had a small effect
This issue has been fixed in either a future version or updated in a previous version.
