Nanny invasion! (Bug)

My game is having a bug right now where nannies keep spawning in one after the other. 🤣 Like I have a about 7 active nannies right now. I have infant triplets, a toddler, and a child so like I'm not complaining per se but I'M NOT PAYING ALL OF YOU! My OG nanny probably got stressed and called in every nanny she knows.
