The game will still let you buy food from your fridge. I have a lot of saves that are in empty worlds without community lots at all. I joined the new site a couple days ago and shared the link with some friends who are interested in this challenge so there's a few new members over there as of today. :) I like how it's coming along but needs more people to support it! :D
I'm kind of playing my Rosewood save off and on. I'm also doing a pretty involving Walk of Life Challenge and a couple others so I'm not as focused on this one as much I wish I was but I'm gonna try to be on the new site to help get it off the ground.
