Re: Reaper's Rewards: Research Ambrosia not showing up

I'm honestly pretty fed up with this reaper reward quest :/ It's the second week that it's decided halfway through to stop giving me the options to complete tasks. Last time I had to redo the whole week to get the rewards to unlock. Now I can't get the option for researching ambrosia, and it also crashed my main house three times on opening when trying to load the reaper's reward window. 

...I don't use mods, or custom content. I don't want to remove bits of my game or lose some of my data just to make something from EA work. 

The sims in my house have between them max cooking, gardening, and fishing, and fairly high gourmet cooking. So they can complete the tasks, the game is just not giving them the option to do this one ☹️

I have tried different households and different lots, also PC and phone for multiple sims. But the option for the task with the plumbob isn't even coming up for it now. It's just acting like it's completed when it hasn't, and the reward is still locked.
