I did a mission with a higher level team mate then me. When we finished it, he said he could turn it in and get the rewards, but it's still greyed out for me. Specifically, it's hide and seek. He got the rewards, after we defended the computer core from the Klingons.

For both of us it still says, continue- refined behavior, but that just brings us back to where hide and seek began in the Lackey system.
