[ROM] Sim can't eat Mac and Cheese from the cauldron (Ingredients present)

I am also having problems trying to cook Mac N Cheese in a ROM cauldron. I am in InnisGreen, using a Spellcaster, Mermaid & Fairy (yes all in gnome suits). My lot has Simple Living Lot Trait turned on. 

The Mermaid & Spellcaster already tried to cook. They both had ingredients but got white goo in their cauldrons. So you see here the Fairy is now trying to cook with Flour and Cheese in their inventory pockets. 

But their cauldron is also white.

And no one can collect the white goo. It's just marked as "discard content". 

So I cheated the Spellcaster to have level 10 cooking skill then bought Meat & Tomato. With Meat & Tomato in their pockets the cauldron is the correct color when I try to cook Chili instead of Mc N Cheese.

And everyone can now eat Chili. The neighborhood ghost even showed up for a bowl. It was nice. 

So I turned off Simple Living and threw away all the ingredients I had purchased. With the lot trait off and no ingredients when I try to make Mac N Cheese on the same lot with the same cauldron the goo is now yellow and the gnomes can eat again.

I did notice however and this might be useful, when I buy the Cheese from the "Fresh Finds Grocery Bag" (from the Kitchen Clutter Kit) the plate appears empty. When I move the cheese from the bag to my inventory pockets, or to the ground, only then does the cheese actually appear on the plate. This happens when the Simple Living Lot Trait is turned on or off. No matter what when I buy the cheese it doesn't appear to exist until I move the plate. I'm from Wisconsin and can confirm this is unusual cheese behavior and needs to be addressed.
