Map node is complete on Atlas. A path exists. But.....

Map node is complete on my atlas. A path clearly exists to the next node. And yet it is grayed out. Literally nothing I can do, and an entire huge section of my map is forever locked to me due to this bug.

I'm sure others have experienced this. It's pretty frustrating and ruins the mapping experience completely based on how time intensive it is to explore this thing.
