In addition to the incorrect % completion issue, I had ran into a couple of other bugs:

1. On a 2nd or 3rd tribe, the food started with 0 rather than the normal 60-70.

2. On a 2nd or 3rd tribe, I found that some trips with honey yielded 0 additional food.

Both were on a Window 2000 T40 laptop. I did not have the issue when I had a single tribe on a T60 laptop.

Those were the trial version since I am waiting for Big Fish to get it since I was busy recently and have now accumulated about 6 credits and need to burn some of them.
