As unfortunate as your circumstance is, I personally am not bothered by it, and would actually be upset if Zynga "fix" it. Everything has another side to it, and this problem does too - particularly in tagging in En Garde Events.

Unless you can run 24/7 without sleep, you will, in one way or another, accrue more than optimal amount of spirits while you sleep. And when you have tons of spirits and want to maximize your points, this double battle thing becomes immensely useful. I'll admit to using this "glitch" numerous times during the event, and this resulted in me getting Planetarium (I am a free player btw). The max times you can spam click (in my experience) is 5 battles.
