Somehow--and I really wish I knew how--My rascal got stuck in the waterfall down near the mausoleum. It was early in my game and I was still building a lot of huts and harvesting the noni bush. It was fantastic to have her out of the way. My villagers just worked all night with very little interruption.
I suspected that if I closed the game she would be unstuck when I started it again. I actually considered leaving the game open all night. I really wish I had done that because she was unstuck this morning. Ugh!
I'm going to try the "fix" mentioned upthread. Hopefully it works for my village.
It worked! Thanks, OptiTron!
