I've been doing freelance missions to get XP and money. Some of them, taxi and ferry missions, give you something to shuttle to another space station or planet. It goes in the "items" inventory and takes no space. So far, so good.

The problem arises when I die while doing one of these missions. I reload the game, the mission is cancelled (or at least, I don't see any objective markers in space or in the starmap)... but the items (either cargo or passengers) are still there. They don't take up cargo space, but they're cluttering the UI.

Is there any way to get rid of these phantom items?

EDIT: freelance missions, not side missions.
