Characters don't always harvest resource nodes right away. This bug has been there for a while but I never remembered to report it, so here goes.
Especially with survey nodes, the Interact button will grey out when having pressed E (or your preferred keybind), as intended. The character does run to the node, but then does not harvest and stands idle. Screenshot attached.
It's a minor annoyance, usually running back and pressing Interact will fix it, but it still shouldn't be that way
All best,
