For Pi Canis - Path of the Warrior, it's not possible to complete the optional objective for Pi Canis Sortie Beta - Transport Raid. The main objective is to loot 3/3 cargo ships, while the optional is to loot 5/5, but the moment you achieve 3/3, the mission ENDS, and the optional fails.
All you have to do is ignore warping out, rush to the next set of transports and disable them before they reach the warp point. Which is likely why the mission failed.
If not, you likely destroyed the transports. I recall when the mission was new, I destroyed some of the transports and the mission failed.
I've disabled all six of them, destroyed none, and killed both escorts that showed up. The moment I looted the third one, the scenario ends and the optional fails. Beaming aboard any more after that does nothing; once it ends, the optional has failed.
