Here is the situation:
I am at the Willow Shop where the two guards stand.
My win/loss count at that time was 8, 3.
I created a fight mix and fought the first guard.
At the end of the fight I got my xp and my win count boosted 9, 3.
Now I attack the second guard....and I lost.
At the end of the fight, however, my loss count did not increase.
I fought the guard 3 different times and my loss count remains at 3.
