@Chani posted this in another forum thread in relation to that there will be NO Cooking Grid available on Monday.
Which I think is extremely unfair on players.... especially those players who have invested gems to gain all the ingredients quickly.
The Cooking Grid will expire before the Rewards do.
I don't know whether this means that the repeatable mine & Ingredients Spinner will also stop working on Monday also.
However I'm assuming as the Cooking Grid is going to expire on Monday that it seems pointless to continue to clear the repeatable mines & collect ingredients.
explains, with some bizarre reassurance at the beginning that the "event" stays open (by which they mean just the rewards bar).
