Operation Queen Bee - I'm Stuck!

[riverrick]

I'm at the end of "Operation Queen Bee" and have captured the leader and eliminated all hostiles, checked and re-checked every room in the two buildings but the mission won't end. I've run over the grounds and looked everywhere for a hostile that I may have missed but no luck.

What am I missing? I seem to have completed the objectives for this mission but my partner just stands in one place and it doesn't end.

Thanks
