Not sure if bug but i think worth it to submit.
With 100% per cycle baseline +0.2% change makes zero difference. I made a test colony and dupes with and without trait filled their bladder simultaneously.
Was this meant to be +20% per cycle(+0.2)?
1. Make fresh colony with 1-2 dupes with small bladder trait. 2. Wait until cycle 2 for them to make a mess. This will drop them to 0%. 3. Observe how thei bladder fills simultaneously = trait have no effect.
