Sims 4 high school

Hello! I have played the sims 4 high school pack for some hours now, and i have discovered that things don’t work like the should. For examples the prom just gets canceled because of the other events and holidays that occurs on that day, other sims asks me to be their best friend even tho I don’t have a relationship with them, my sims gets crushes on other sims very easily, and even tho I have said no sims ask me time and time again to go to prom with them (like minutes after they asked the first time). I hope you can fix’s this soon. There is also some glitches in the base game, like my sims don’t use the sink that belonges to a bathroom, instead they go all the way down stairs to use the kitchen sink and they use the pool when I click on the need bar, instead of going to take a shower.
