I've used the guide, but I'm still unable to figure out where I'm meant to go. I've been through the tunnels (1, 2, 3 idk if theres a 4th), and headed south-east in every section
if you are trying to get to Morgan’s home, I believe you have to go through the cave that leads west and once you step outside, head east. There should be an opening on the east side that takes you to the next map.
