SPOILER!!!!!!!!!!
You can still make the chief create food. It's 24 hours of REAL time. I have one tribe that I just started and I keep them paused almost all the time. I unpause them every 24 hours of real time and have the chief make food. (It's only been 2 days). It's a good way to get them a bit ahead!!! I don't mess with the time on my computer anymore because if you have to put it back for any reason then the chief won't make food until you get to 24 hours past the last date you had on the computer. For instance, I was in a hurry one day to get my kids with some experience before they turned 14 so I kept pausing the game, moving the time forward 24 hours, unpausing, make food and teach kids, pause, move time, etc. I got to June 2nd then I had to pause and turn the time back to normal because it was messing up my work. Now the chief won't do anything extra until June 3rd!!!!!!!
