Ideas
I’m experiencing part of this issue, but not exactly as it is described here. Here’s what happens in my game:
Context: I have a pottery club that meets on a small business lot.
If the business owner starts the club gathering, everything works fine (except club members constantly try to bake a white cake in the owner’s kitchen and then abandon it halfway 😅).
If a club member from another household starts the club gathering, it breaks.
More details:
That non-owner Sim is outside the small business, and the game says they must buy a ticket to enter.
The club gathering is running and other members are inside doing activities, but whatever they do, club points don’t accumulate.
My Sim is unable to join the club gathering.
If my Sim buys a ticket, they can use the pottery wheels (etc.), but those actions count as business activities, not club activities.
BUT…
Whether my Sim bought a ticket or not:
If I leave the household to the Worlds screen and then immediately jump back to that same Sim at the same location, I now find my Sim outside the business again while the club gathering is in progress, and this time they can enter and join the club gathering normally. And club points DO accumulate.
