DE, the Star Chart XP is going down with each node you add. Pre-Fortuna update it was 27,627 but Pre 25.0 it was 27,579 total xp and after 25.0 (or currently is) 27,501. Why is this number going down? Shouldn't it be going up with more nodes? At least it should stay the same.
The odd number that star chart leaves is in between ranks so it may never be noticed unless someone had a document to calculate xp.
