On of my Dupes got Diarehea, when that happens you also see a floating text.
The floating text for me had <style> tag in it, it went by pretty fast so i couldnt make a screenshot.
Alertmessage "Braynen was infected with Diarrhea by eating a Mush Bar"
Screensht shows her stats
get a dupe to get diarrhea, maybe from a mush bar, check the floating text, i had 1 full ration box so maybe she ate it off the floor
