The Sims 4 Reaper's Rewards is a limited-time event running until November 19, 2024, but it's down for a lot of players, which is understandably frustrating. There's a lot to do when you get this event going: you can summon the Grim Reaper, complete specific tasks to earn unique rewards, and more. There are a few different reasons why you might be unable to trigger or complete the event, but there's one main reason that requires your attention. Here are the details.

Very important: make sure you back up your files so you have something to fall back on if something goes wrong.

If you have been using mods or custom content, removing them seems to help trigger the Grim Reaper's Rewards event in The Sims 4. To make it easier, disable mods in-game instead of manually deleting the mods folder. If you have Better BuildBuy, disable organized debug first.

Also check for updates regarding mods that appear to be breaking the user interface of the Grim Reaper Rewards event.
