Hi, New player. just started online, after going to Valatine and getting the first quest to kill the robbers in the forest where you get the treasure map and going to that area and looting the chest it does not allow me to move too far away from the area, so clearly I'm missing something else to do there, I have been running around that small area for ages looking both in Dead Eye and normal climbing the cliff face and going round the back to the chest, but to no avail. What am I missing???
