10 years of The Sims 3 - Happy birthday!

Sweet lord of grilled cheese! it's going to the sims 3 10th birthday?! This memory is pretty much recent (despite being the worst, but end up being a favorite XD). I have the sims 3 generation pack (it's my favorite one BESIDE Seasons, supernatural, late night (they first introduce vampires while supernatural is like "Alright, we'll just improve vampires, but add a annoying sparkle if they have the lifetime trait for vampire be immortal and doesn't age"), and University.) and then the prom thing show up that it's going to happen on monday 6 pm sims time. I get my male sim to ask the female sim (aka me with Pink hair and eyes, and a vampire, but doesn't know that which kind of cause her to wear "emo" clothes, but the reason she has is the identity crisis for what kind of species she is since she's not human.). OFC she accept Since she's been living together with him and his mom since they we're TODDLERS and Best friend, which turns into bff. On the night of prom, everything went VERY well. They got their first kiss, going steady aka bf and gf, and became prom king and prom queen. Once prom night is over, they went home. Once they arrive at home, I decide to edit the house. Then, here comes the invisible interface in build/buy mode. I tried press from f1 through any shortcuts that the manual states. I kind of went insane for at least five seconds and I was like "You know what, I'll just start fresh and remove the sunset valley residents since I rather have supernatural sims than normal sims." and I did just that. Luckily, after I age them up to teens, the prom will start on Wednesday 6 pm sims time so ye. Holy moly, that was long despite it's 1:14 am in my time, but what can you do.
