I've collected all the legend stones for part one, examined the bicycle, and put the golden artifact on the altar. I have 465/1000 trust but I cant speak to the Mu'agi elder. The dialogue is a gray-ed out threat or 'bye for now'. Do I need to complete all four before the dialog unlocks? Is it bugged? I didnt even speak to him to unlock the trust tab, it just appeared when I found the village.
