While trying out the Fallen, I appeared right beside an Ominous Spiderweb. I built my first town and walked right over to destroy it, and a bunch of spiders appeared. I misclicked on my attack attempt and went into my new town. The spider was right next to it. When right-clicking on the spider to exit, my channeler appeared right on top of it, not attacking. It was the last of my move. When I ended turn, the spider fled.
