I spoke to Mol before defeating the gobbo camp and said I might help her steal the idol. After defeating the goblins, I spoke with Mol at the grove again. I told her I didn't have the idol. She was like, "shoot, we could have sold that for a lot!" My journal updated saying "We decided to keep the idol for ourselves." Problem is, I never touched the idol and never intended to. I'm not keeping anything for myself - I simply changed my mind and decided not to steal it.
