When in auto after the catering is finished the menu (3) shows fuel truck requested but it never comes.
Please clarify the sequence exactly. You don't say if you started with Boarding or Deboarding, which is important to know.
Also the boarding (4) no longer waits for other services to finish before starting doesn't even display a message "waiting for other services". I have tried this with different airports (default) and planes with the same results.
That's not a bug, of course. It's a new feature that has been added with the PREVIOUS update, which has been requested by many users, and it's the ability to have some services like boarding, catering and refueling all running at the same time.
