@PugLove888 So I tried today with an old save of a big human family, I waited for the toddler to have her birthday and I was able to throw a birthday party normally. I do not have time to test with more saves and more ages of sims right now, but it seems that the problem is indeed with vampires. However, not only teen vampires as you sugessted, but also toddler and children.
@Anaideiae, there is another thing I need to ask... can you throw your Birthday Party for your Vampires at night?🤔
Thanks! 😇
@PugLove888 Hi, sorry, it has been a hectic month so I did not check the forum. I was not able to throw the party any time of day, I tried at night multiple times with the same result - no one in your household is having their birthday.
