So my main issue i get regularly is if i pull an outside view on the HST, 50% of the time when i go back into cab view it keeps the outside noise.....very annoying. Also when i have reached my destination reading/paddington......the bar tells me my achievements etc but then the service bar top left corner dissapears.......so I dont know when the train is next due to depart, very annoying! It would be useful to have a button to exit that service then can go back into the seat and see when it departs? As i spend alot of time trying to find a reasonable departure.
Know what you mean regarding the sound issue. It's quite annoying, what i do is save my services very often and once it appears I'll simply restart the game.
Yes, it's a very annoying problem. Not only happen on the HST, in fact, I think it's happening on all trains. It's very remarkable with Talent 2 too, for example. This problem, together with the floating seats, is for me one of the main issues of the game. I hope they can fix both.
