So I was farming, and the CC was near the edge of the base. I dropped a barb and a group of archers ran out. I lured them over to the corner and dropped some of my own archers to dispatch them. As the last one was dying I unleash hogs to storm the base. Then a wizard and several more archers popped out of the CC as my hogs ran past it. I got some loot, and 1 star, but it would have been an easy three star if not for those extra CC troops. Is that a normal occurrence?
