I am puzzled.

I have 3 tribes, and ring the gong for all 3 every chance I get. Overall, I've had an even distribution of good and bad results. I've always been able to see the results of each effect, until now.

A couple of days ago, I got "The gong grants luck" and I've yet to figure out what effect that produced. I couldn't find any changes in my villagers or the stats. Of course I can't remember every detail about all the villagers, but didn't see any obvious differences.

Have any of you had this experience with the Gong?
