Map node not accessible Hilda Questline

Second part of Hilda Questline (Great Beasts) spawned on a Riverside node, but can't be accessed by any outside node. It's a part of 3 maps that cannot be accessed.

Still inaccessible, everything else in radius cleared.

Found posts from earlier leagues about similar issues, but usually just there being a few maps that are unlinked and unclickable. Only difference is mine just happened to be required for a questline.

Day 5, still not seeing other references to this problem.
Found another older post where someone said that they had this happen and their "missing" node was covered with a mountain or something and to click around. I've hovered and clicked over every possible spot, still nothing.
Just stuck with 3 unconnected maps and still unable to continue Hilda questline.
