Can't host a party
Hi.
I'm at level 23 and I have 2 sims. I haven’t been able to host a party yet. I read somewhere that in order to unlock parties I would need to throw a birthday party or do a party tutorial or something like that, and as I understand it this usually happens after choosing a new trait. Both of my sims have four traits already. I never had the option to do a party tutorial or anything like that. When I click "Host Weekly Party" all the options are grayed out, the Birthday Party says "*sim's name* hasn't chosen a new trait this week" and the other themes say "Must host a Birthday Party first".
How do I fix this? What do I need to do? I tried unlocking a third sim, but when I click on the "unlock $175" nothing happens. I have enough cash to do it, but I don't know why I can't click it.
Please help! ☹️
