Unfortunately Jack-o-Lanterns were only active for V18 Halloween :(
There isn't anything to make with Pumpkins yet but we'll add that in another version.
Thanks
Thank you, Denki, for your response and for developing such a wonderful game. I had downloaded V17 and then V19, so I missed out on V18. I look forward to creating foods from pumpkins such as pumpkin pie, pumpkin bread, and maybe even pumpkin soup, pumpkin cake, or even baked or roasted pumpkin. We need to keep our Folk happier for longer times. Our players too. ;)
