Dupes keep losing track of needing to go to the bathroom while eating

Do you have enough downtime in your schedule ? 2 squares is a bit low when dupes must travel a bit. 3 is nice, and 4 is even better for dupes that work far from the main base.

Dupes won't prioritize going to the bathroom during break time, that's what the bathroom break tiles are for in the schedule block.

I don't have the game booted up ATM, so I'm not 100% sure of what it's actually called...it's the cyan tile. :3

 

2 squares bath, 3 leisure, 2 bedtime.  Some of them are gapped but it used to be that 100% bladder would get them where they need to go, even during leisure time.
