Mainscreen economic graph issue

The economic graph does not display the Yor's stats correctly. I started a new game and it showed the Yor's information, hadn't 'met' them yet. Saved game and restored, the graph no longer showed there economic information. A little while latter, I 'met' the Yor, but they don't show up on the economic graph (the other graphs appear fine) :notsure: Game is saved, if that would help...
