In my first tribe I had a chief die and found a new one immediately she was I think 53 yrs old at the time. Just to see what would happen I put her on the food bin and she made food. (The last chief had just done it an hour or so ago.) I then tried to lecture the kids and she did that too! I didn't have level 3 leadership yet so I couldn't try that. I think each chief can do everything once in 24 hrs meaning if your chief has done his/her duties for the day and dies a little while later and you find a new chief before the 24hrs is up he/she will do the same duties again. Like the clock starts over for each new chief.
