Recently, I've noticed that my goblins have been panicking around a lot and interrupting their jobs. At first I thought it might be because they get really hungry or something, but I checked the Goblin Camp Wiki, and it said that it's because they saw an enemy. I can narrow down it down to the bottom right side of my camp, but I checked around, and I don't see any enemies on the map. Why's this happening?
