Re: Cancelled Grim Reaper
@Jomoon017 You can move accountDataDB.package, which is in Documents > Electronic Arts > The Sims 4, out of that folder. This resets your progress in the tasks, but it doesn't delete any rewards you've already claimed, or points you've earned.
Do NOT delete this file—it also holds data from the first round of login events. Instead, just set it aside for now, and put it back (delete the new file) once you've finished the tasks again.
