What are the new mastery symbols on planets exactly? I seem to have one that constantly changes planets and have no idea what it means

**EDIT: it seems to indicate that you have all nodes available.

I had assumed it indicated that you complete the planet on steel path.

The Kuva Fortress moves around. Are you sure it's changing planets and not that the Kuva Fortress is just movin'?

It doesn't actually mean you've completed the all the steel path nodes on a planet, at least for me, it means you've unlocked all steel path nodes for the planet. Whether that's what they intended, or that it's a bug, who knows

After reading some comments, No One knows what the hell it means...

From what I've seen, the steel path cleared icon shows up when you can access every node on the planet, even if you haven't done those nodes and completed the planet. There might also be some logic with how junctions an connected planets work, but afaik it's just the nodes.

Reasoning is as follows:

Ive yet to unlock all the Europa missions, it says not completed.

I've yet to do all the nodes on jupiter but at least unlocked them, done all the junctions, says completed.

I've yet to do all the nodes or the junction for ceres, and haven't done the junction, also completed

I have done all the nodes but not the junction for earth, also completed

When I unlocked the last mars node, it became marked completed

Kuva Fortress moves around and which ever planet it's next too is the planet with Kuva flood and Kuva Siphon missions.

Really dislike this addition. With the way the camera moves around while looking through and picking missions, it just feels cluttered and way to big.
