[1.21] Mission Bug - Family Heirloom

[aggrressor]

Hi All,

I ran across the following bug in the "family heirloom" mission. Game version 1.21 through Steam

Steps to reproduce:
1) Accept the mission
2) Fly to the mission area
3) Save the game
4) Attack the target ship, the pilot must eject and the ship must stay intact (might take a few tries. reload and retry as necessary)
5) Capture the ship containing the mission cargo
Expected result: The mission should complete/go to the next stage
Actual result: The mission still states that I should destroy the ship that I now own.

My only options now are to either terminate the mission if i'd like to keep the ship, or to destroy the ship and complete the mission.
