The Tiefling child Mol has been moved from her hideout beneath the druid's enclave to being out in the open next to the training dummies, but all the dialogue for her still says she should be down below.
If you go into the cave where Mol should be all the tiefling kids will be there, and then they will start leaving as you start walking up to them. On top of this if you talk to the tiefling child you can save from the harpies says "I wish the harpies would have killed you" regardless of how you handled that situation, and I can only guess its somehow connected to Mol not being where she should be.
So that's where she is... I was wondering why the hideout was empty when I got there after dealing with the harpies. I did find her there during my previous playthrough with patch #2, but now with patch #3 there was nobody home.
