[FIXED] Sim doesn't age up by blowing out candles

My Sims will not age up by blowing out candles. And random sims keep coming over and baking cakes. When they bake the cake it is stuck in the fridge and can’t be used. When the sims bakes a cake the notification for blowing out the candle would disappear and the sim would act like its distracted or just would do something else.

I tried it several times. I repaired the files in origin, tried again to age my sim up and the same thing happend. 

I have come to the same conclusion as CaesarxAntony.

I had a family of five sims.

A child, a teen, a young adult, an adult, and an elder.

When the child, a female blew out the candles, she aged up successfully.

When the teen a male blew out the candles, he aged up successfully.

When the young adult, a male, blew out the candles, the same thing happened as with the original poster., the guy teleported abit back and nothing.

When the adult blew out the candle, she aged up successfully.

So, this issue seems to be with young adults only.

Now this save was created for the testing of this issue only, so it was created after 1.68.154 patch.

A savefile is available if requested.

Adding my own (mod-free) testing:

All Sims can age up by celebrating, but

Choosing "Age Up Sim" to select a Sim other than your currently active Sim, results in them acting like they're aging up but they do not.

Having the same issue, but with children sims. I am doing a challenge and it's time that I age them up, but the cake simply doesn't work.

So it isn't an issue just with teenagers, I think it affects all ages...

For those affected by this issue, did your sim have self-assured trait?

I made another attempt where I made a sim and three kids, one with each of the same trait my affected sim had.

Art Lover, Self-Assured and Outgoing.

All three grew up to become teens.

The one who got the Self-Assured trait did not age up after teen though.

Ok, then that is not it.

Yes, I did make a few attempt with the same sim, both before and after succeeding with other sims.

I was thinking it could be trait related, but seems not.

I can't get my sims to age up with a birthday cake!? I have closed out of the game made sure it was completely updated and nothing is working.
