No planes are taking service round when they arrive at stand, ramp agents go out, waiting for the plane but it says service round not requested and the ramp agents go inside again. I have filed a bug report (ACEO-2543)
I have seen same issue.
I’m a little disappointed with the update. It seems like it introduced a bit more bugs for me then it solved. Oh well. I have a lot of faith that you will fix them soon. Also, the new vehicles look great!
