Adding to the many "glitches" already being found, here is yet another (intended?) end of scenario "killer"!! After running the entire scenario, you arrive at your final two moves, uncoupling from your train to run to your "stop" checkpoint, and moving to a different track to make way for an oncoming train. The issue here is that "stop" point, or lack thereof, due to the fact that it is labeled as "go via", which to player means pass through, not stop! Once you have passed through the checkpoint you lose any ability to throw switches, as necessary, to get to your final destination. Game over, unless......create a scenario failure and reboot to your last "good" checkpoint. I'm not certain if this was an intended thing, or an error, but I'm hoping it is just a correctable error. Over all HSC has great potential but there are MANY issues to be worked out yet. For the players it is extremely frustrating to encounter them at the end, or near end of an operating session.
