Sim gets bladder thought bubble with no reason

I'm having this issue but with JUST the bladder need. Both of my sims in the same household bladder need won't decay at all. I think I noticed this after I gave them the steel bladder reward, which says "rarely have to pay attention to their Bladder need". Both my sims should still have gradual decay of their Bladder need, but it has been permanently filled to max since I gave them both this reward.
The weird thing is, they still get the bubble over their head saying they need to go every once in a while and then proceed to go to the bathroom but then the action cancels, I'm assuming, because the need is already full.
I included a screenshot which shows her with the toilet emote, making a tummy ache motion on her belly, and her automatically lining up to go to the closest bathroom. Then as soon as she walks in, she walks out and the action cancels. You can clearly see her bladder need maxed out.
I've already reinstalled the game, and repaired it, and cleared the cache. I will test this out on a new save and my old files as well and update below here.

I have a family of 2. One of the sims often complains that he needs to use the restroom, when his bladder is full/the need is green. 

I'm experiencing this too and I play on Xbox. My sim keeps complaining about needing to go to the toilet but her bladder needs is in the green.

this is happening to my sim since he became a teen as well. Complaining he needs bathroom but his needs are all full. now i dont know if he needs it or not without checking needs

Hi us7czgwx8n3x​ 

Since your Sim is not a fairy, I moved your post out into it's own thread.

I though there was another general thread but I have no clue where that went.

What platform are you on ? 

I'm on Windows. BTW I also tried saving the Sim to my library and placing them back — it didn’t help.
To investigate further, I installed MCCC to check active and hidden buffs, but found nothing suspicious.
What else can I try? Is there any kind of debug log where I can see what exactly triggers this thought bubble above the Sim’s head?

The exact same thing is happening to me. I suspect it's something related to the Enchanted Nature pack and the activation/deactivation of the affliction system. I haven't been able to find anything suspicious with MCCC either.

This is happening to my whole Sim family.  Bladder need bar is full, but the toilet thought bubbles pop up around 8 hours for everyone.  If I let them pee (although they don't need to), it goes away for several hours (probably 8 but haven't timed it).
