Mr. Network Pesci, thank you for the feedback I will explain the things you spoke of.
In all honesty there is not really a practical way to prevent that ship from being sold in Askonia. Currently the way the vanilla game is setup is that the Independent Traders have all ships available to them and deliver them at random to the Askonia station, this is intentional behavior by Alex until he sets up the factions "proper". For a while I had a special every frame script that would remove unwanted things from stations and this worked, but it has issues that were two fold: You could still get the prohibited stuff by killing the supply convoys heading for Askonia before they delivered them to the station, and it also causes a lot of crash errors with some other mods that had every frame campaign scripts if they were ran at the same time. So this script was scrapped since Alex will solve this issue proper himself at some point, and so it was more trouble than its worth to try and solve those two problems. Unfortunately for the time being I recommend just having self control and role playing. As for the ships appearing in the campaign as intended, right now this is really just a "demo" with them in missions and no mind payed to campaign integration. So people can have fun with the ships, and they can be integrated into Uomoz's compilation. TIM pack will not be updated for a little while as I concentrate my efforts on my main mod project. When that is updated (and it will be an awesome patch) TIM will be my primary focus instead with proper campaign integration for all the "vanilla" ships, the Pirates using their new stuff properly, and the Tiandong guys with their own agenda
Also about that mission, holy crap you actually almost beat it? For all intents and purposes I designed it to be 100% impossible, if you ever beat it and even better if you have a video recording of it I will sing songs of your badassery!
