I see this option, but if I try to get my sim to actually use it, I get an error stating that there's 'not enough funds to continue making food', no matter how much money my sim has. Unless 10K isn't enough... Which would just be weird.
Is there a patch or anything for this problem?

Ice cream? I may be mistaken, but I bet that's a custom food item, in which case you'll need to seek support for this issue from the creator.

That better be some good ice cream!

I never downloaded UCC ice cream. The option actually says '*Food - Ice Cream - Instant Meal - Menu' This appears under 'make many' which only turned up after I installed OFB.

I have the full game, including OFB, and I've never ever seen an option to make ice cream.

It's possible you have a different version from me that includes ice cream, but it's more likely you picked up a custom ice cream in another download without knowing it. Might want to use the Clean Installer to scan for hacks you're not aware you have.

Maybe.
I installed OFB over Double Deluxe with Nightlife. And I will scan for hacks. Thanks.

After scanning - can't find anything with ice cream in it o_o

Had an idea... searched... AHA! Found it.
Yes, it was hidden in an object.

Awesome. Happy simming!
