I had a very strange experience this morning. I was doing my daily census (as if I don't have anything better to do) and when I checked one of my elderlies who was 64 yesterday morning. Imagine my surprise when I discovered that she was 58. Strange, huh? The gong had nothing to do with it. Yesterday's gong present was "takes away youth" so she should have gotten older on the spot instead of younger overnight and it didn't effect anyone that I could see anyway.
I was reading a few of the posts about making elders as I was searching to see if anyone had had this happen to them and I saw the one about the gong granting knowledge. I had a guy villager made an elder on the spot when the gong granted him knowledge in 2 skill areas. It was very strange.
