In this save https://drive.google.com/file/d/11ZZVFw ... sp=sharing you can find multiple ways to break barter missions:
I have a barter missions for 100 nostrop oil and 99 medical supplies (Story Mission). I have another barter mission for 1846 nostrop oil and 181 medical supplies for the same station
The H has enough of both to satisfiy both missions (1946 nostrop oil and 280 medical supplies)
As soon as the H arrives at the station the dialog will pop up. Everytime I load the game, it picks one of the two missions for the dialog - but most of the time the story mission. You can then choose any given option as often as you want, all of them will queue up in the commands for the H. If you don't spam but wait until the correct amount was delivered of both wares, you will still get asked about the deliviery for the same mission over and over again. No offer of energy cells or changing to the other (unsatisfied) mission. You can empty the H that way completely without completing any of the 2 missions.
Also, no mission will track any progress, but that is true for all barter missions - at least to my experience so far. But at least usually you can finish them, if you keep track yourself.
And you will also notice, that the dialog will mix with the banter of Nila Ti and Boso Ta. The flashing background, "Press F" and "Confirm barter delivery" will remain during the whole time on screen. Most of the time you can't answer the barter call until the whole other story banter is done. Sometimes the flashing background and the text will even remain, when you move the H away from the station as shown here: https://i.imgur.com/Z9EWKmUb.png
