Special cargo missions impossible?

[Q]

One of the first things I did to find the cause was to copy a standard cargo mission job and make it event triggert. It creates the random job as expected but again no cargo is loaded and in the job list says you must load cargo X at the present location. Therefore it is not the job itself but the event triggering that causes the problem. You should be able to reproduce this without any special job file.
And no, I got the full game now at version 1.15.
I made now the job for one special site available only and created this new site for the planet I wanted. This works. However if the player does not accept this job, the game story will then of course not continue.
One very basic event I miss in starfury is a "players choice": give two or more options which the player can choose and that will lead to different further game stories. And a "NOT" condition for triggers would be very helpful too.
