I just recently started playing again, and noticed an issue that I haven't seen mentioned elsewhere. When the menu button is pressed the chart with speed, grades, etc. shows up. However, after a short interval of playing time the green line, indicating your speed, moves from the left of the screen to the right of the screen, and then disappers completely, for the rest of the scenario. It only shows up again on the final scoring screen that displays how well you did. Sometimes I also see crazy numbers for the speed limits like 9,123,456,780. At first, I thought it was only a problem with SPG, because it was redone or whatever, but it also happens on NEC-BP, even though that one is obviously much newer and also fancier with station names displayed. Is this a known issue? If so, is there a planned fix?
