Working on the Mission: "Rush Job! Ores and minerals needed."

I've delivered all the required items, and have gotten confirmation of all of them, but the mission won't end. At some point the timer disappeared , but I have 3 hours to spare.

I know the basic solution is to abort and re-take the mission, but I had gather quite a number of items that I wouldn't like to lose/repeat.

Any suggestions to kick this mission back into gear?

Well, after a short break i relogged again and poof: Mission complete.
