When the CNC hacks into the last remaining building the attack finishes and you end up with 98% and 2 stars, this is before 3 minutes has elapsed and you still have troops. This is frustrating as your attack has been successful but you don't get the full reward of totally destroying the base, a wasted attack in alliance wars. This has to be addressed by the developers so that this situation cannot occur.
