Gave this a try after a long hiatus, and it's been 3 whole days until I ran into something that has me stuck or at least confused.
Got a Spider Nest mission in Ankara. Go in, shoot all the spiders topside, and then get to the unexpected part 2 where you crawl around in the Spider's nest looking for the queen. Down go the assault rifles, up come the pistols and flashlights, and after stumbling around and shooting many spiders, I find what I believe is the queen, a plus size monster who takes up more than one tile. I shot her a bunch of times, and she went down, but the mission isn't ending. I think I've killed all the spiders, but I can't seem to figure out how to close the case; sending everyone back to the green tiles and aborting gives me a "Case not closed", but there doesn't seem to be anything else to do.
Any help guys?
