I know that this has been a problem in the past.
Please could you try this in Singleplayer and let us know if the problem continues.
If it does, then this is a problem that needs to be submitted to SCS Software.
You can find the correct Forum here: https://forum.scssoft.com/viewforum.php?f=40
Please let us know if your problem has been solved.
Best Regards,
