I'm not sure if this is in the stickies, but I could be wrong. Anyway, I think that whenever you deploy a wall breaker, you should be able to pick which wall they target. For example, when you drop a wall breaker, the whole battle pauses and it asks which wall you want to blow up. Once you choose it, the wall breaker targets it. I have had many problems with my wall breakers blowing up the wrong wall and in some cases, I even lost a battle because of it. Well, let me know what you guys think! Thanks for reading, bye!
