Random Milestone Moodlets

Sorry if this isn't the right place to say this, but after today's fix, I no longer have this problem.

I created a family and moved them into a house, and immediately the teen son was reflecting on a milestone! He’s had several different ones since then that are also not in his milestones panel

Four different households are experiencing this in my main save. Bladder blunder, sting of rejection, and hated moodlets on adult Sims who have never experienced any of these. I also just recently had my teen Sim experience the 'smooth sailing' love life milestone even though she has never had a single romantic interaction.

Brand new save file, played one sim day, sim has sad moodlet for milestone reflection - hated and sad "You can't be friends with everyone, but Esther's made more enemies over her life than she would like".  Sim has two friend.

On PS4 so no mods

My single, childfree, newly created sim got the moodlet for feeling rejected/upset for not being the favorite. They have nobody they could be the 'not favorite' of, and nobody that could be the favorite, but boy did it mess up her day.

Bladder failure one for my married sims who also never had this happen. I was so confused and checked their milestones - nothing. Then I switched to another household, and suddenly the exact same bladder failure milestone appeared! Again, no history of such.. 

I've had a sim have fear of repeat alien abduction that was never abducted.  And now my sim and her wife both have bladder failure moodlets when they were both asleep, all night, with nary an accident in sight.  

Same for my married couple who've had perfect relationship... It comes up constantly and it's so annoying that it keeps dragging them down for no reason :(

This is happening to me too! I was so confused and assumed maybe I just forgot these things happened but then its done it with a fresh sim too.
