Reaper's Rewards event unavailable ?

Thanks for your response. Sorry I didn't make it clear in my original post, I thought my screenshot included the event pop-up tag like this:

Yes, the in-game tasks are not displaying, and the event tag remains as in the new screenshot. When I do click on it, the full event screen comes up, as the original screenshot, but I am unable to see the current task. I tried removing mods, clearing your recommended file 'accountdatadb' and the standard L files suggested in the mod comm., creating a new save, and repairing the game. I am still unable to have the remaining tasks displayed. 

Thank you for your help!  I had actually tried this a few days before and didn't see a change. However, I tried it again tonight and was able to get the event tasks again. It could be because it was already a newer TS4 folder since I had replaced it once before. Regardless, thank you.

I have finally gotten my tasks back! I removed the Sims 4 folder, repaired the game, and created a new save. After the new household lot loaded, I got a pop-up for the week 6 tasks. I exited the game and replaced my old save files, and I was able to continue the event in my current save. Keep in mind though, I had removed the Sims 4 folder and repaired game twice before I was able to get the event pop-up back working. You may have to try again if this hasn't helped.
