Sol II, M-4, mission "Big order for Premium Silicate Ore", I have delivered the requested 60 units of Si ore, relaunched and come back with more, and the mission has not completed (still giving me the abort button and still listed as current mission). When I returned with extra after the requested 60, the new ore was not automatically collected. The mission log does state "All 60x Premium Silicate Ore delivered successfully," but no rewards have been granted.

So I'm currently stuck without being able to take another mission, or being forced into aborting this one.
