Fixed: only two fields were reachable in the skill tree with a controller. The navigator collects its targets from a fixed list of markers in the HTML — the skill fields weren’t in it. With a controller you could therefore only reach the weapon card and “Exit”; the skills themselves were unreachable. Now skill fields, the song list in Track mode, setlist entries, mutators and difficulty levels count as targets too.
Deliberately left off the list: the small boon icons in the tree. They only pop up descriptions and would have added dozens of stops on the way to the next skill.
