Battle bug

When you want to get exp without using karma or sushi i always pound some lowbies and steal their treasure :oin Battle. But i found out if you pick a higher lvl then yourself and have just 1 battle turn left. it doesn't use a turn. Because i have tried it many times to be certain here is what to do
1. Opponent is higher lvl
2. He needs to hit you once

and voila you didn't use battle turn, got your exp no cookie used.

I used this a lot in team battle crackdown event. When i have 2 battle turns left, i did a battle and then i had 3 turns so basicly that's free doras ^^

Let me know if this works for you to ( Using a Galaxy s3)
OW very important it only works after every hour!

I think there's a similar glitch such that I use all my battle turn and wait 1 hour to recover 1bt, using the bt to fight for treasure, I get another turn(bt unused) or wait 2hours to recover 2 bt and use it to fight for treasure to gain back all 3bt. Thing is, I find it works only in the first few minswhen I recover the bt
