MRC has a blueprint for both Altagrave EX, and Hell corsair - I'm not 100% sure about corsair, but I'm almost certain the Altagrave EX is supposed to be a unique ship.
In most cases it shouldn't matter - but because how bounty system works if a player has industrial evo they can sometimes get the blueprint for unique bounty ship from planet ruins event (which you have nothing to do with, but I'm mentioning it to explain the bug/feature in full).
Because the MRC has access to Altagrave EX blueprint I'm wondering if they might produce it if a player on MRC commision colonizes a planet and gives it to them.
That being said - it MIGHT be just a weird mod interaction between arma and ashes of the domain question of loyalty - which allows the player to produce ships from the blueprints that faction he's serving owns.
It wouldn't be a problem if it was something you can encounter only with ashes of the domain - but it seems to me that it might be possible to give MRC a planet and ensure that they are not instantly destroyed by other factions - and then raid them for blueprints until you get the unique ones.
It might not be the case though, and just a weird mod interaction. I'm going to test it once I have a bit more free time.
Edit: Also - thanks to that interaction with AOTD I was able to produce Hell corsair - and I do not have Tahlan Shipworks active - which made the game crash in refit screen when trying to put weapons on it - again, not expecting it to work with AOTD, but it might have some other unintended interactions.
