No engine sound after loading up my save game?

Hi all, finally got passengers onboard lol but last night I had to save my game, this morning when loading it up, everything works except for the sound ? Anyone any ideas on this pls ?

I can confirm this, after loading a save game no sound from the bus, i believe that some sounds do work (linke passenger walking inside the bus)

We had one tester with the same problem. We haven't found it yet. But: the sound will come "back" after some time!

ah ok, well I will try that tonight then and let you know how I go, thank you for the replies, I really appreciate it
