I would suggest to create a new thread for that, as that is not the same issue. This thread was only about not having available plane for heavy cargo, which currently solved by buying the premium edition (i know thats kind of ridiculous solution, but thats what it is). A new thread with “No heavy cargo missions” or similar would then focus on that issue. I’m saying this only because if there are more issues raised in a single thread, the dev team will only take one issue (the main issue) from it, as per guidelines. So you have better chance of that being solved if you have a thread created just for that issue.
