If you click on your sim and go to their personal screen to change appearance, you should see an icon like a hexagon, that's where you can select a new trait for them if they've made enough progress to have that option available. Once you've done that, you should be available to host a birthday party with that particular sim 🙂
I'm having the same problem as the OP. It just says that I haven't chosen a new trait this week. I have tried switching traits (at the cost of 5 heirloom tickets, I might add) but it didn't solve the problem.
I've been playing the game long enough to be a level 46, and it has always said the same thing each time I've tried to host a party.
Am I doing something wrong, or is this a glitch that needs to be reported? Also, I noticed on the previous poster's screen shot that there's a 5th trait slot available, and all 4 of my sims only have 4 slots. But if you have to wait for a slot to open up (as I believe someone mentioned in a previous post in this thread), how are some people hosting WEEKLY parties...?
YES! Exactly what’s happening with me. I’ve attached photos to show what my heirloom page looks like and the message I am getting when trying to host a party. How do I get past this? What do I need to do I order to host a party? There’s no button to choose a new trait. If I buy a trait with tickets will that be sufficient to host a party?
This game is actually very confusing. Nothing is explained properly. I’ve had to google so many things just to figure out how to proceed. Why does this have to be so complicated?
@CorkyBebe, I think you might be out of time to host a birthday party for that particular sim. A sim can host a birthday party if you still have the space to add a new trait for them, but based on your photos that sim already has four/five traits and is at the retirement stage, so based on what others have already posted, it's too late for them to have birthday parties. They can host other types of parties still, though!
If I've passed up forever the chance to host a birthday party, how on earth can I ever host a party of any description?
