Event tasks not showing

@amylou3

Fix the game in Origin
Origin/ My games library - right-click on TS4 - option "Repair game"
You have to wait until Origin will fix all packs, not only the base game.

If it will not work - some files in the game folder can be damaged - then try doing a factory reset as described in this post:

I don't work for EA

@amylou3 Is this when you get invited to one or when you throw a party with your active Sim ?

Parties you get invited to don't have tasks (same for dates) and if your active Sim is initiating them, make sure you have prestige events (or whatever it's called now) ticked in the menu. Without that, there's no tasks

@crinrict Where in the menu?

@SenoritaJen They're called goaled events and it's when you choose the party type.
