I'm on the farmer's market level and it says there is one little sister left, but I can't find her and the big daddy is walking around banging on those things, but no little sisters are coming out. What should I do?

I'm not sure but i think this may be the level where if you don't catch the little sister who's escaping through one of those vents, straight away, you can't get her.

She's the one who stopped me from getting the 'dealt with every little sister' achievement

I think this might be a bug. I saw the same thing happen where I was following the Little Sister and then when they got near one of those vents I attacked the Big Daddy but when I had finished it off the Little Sister was gone, so I reloaded and caught her before she went into the Vent.

yeah, you gotta be careful. that happened to me once, exept i hypnotised the big daddy, then i was so pissed that the little sister ran off and even after i killed the big daddy she would come back.

yeah, it sucks major balls
