Maybe a screenshot will show it better. I want the little piggies to exit through that 1x1 hole in the wall into a larger enclosure. However they just ignore it like it's not there, same as the adults. So does that mean they don't see it as a path? I've seen people do something similar in playthroughs so I thought it would work.
