I have spoken to Joligeman, and we have reached the conclusion that he just made an honest mistake. He saw from the damage logs that you damaged the other user first, but he did not check the shot logs in order to see who was actually shooting first. I have reminded Joligeman to use the shot logs in situations like this, and I will remove your punishment.
Since it was just a mistake on Joligeman's part and this hasn't happened before, I see no need for further action to be taken.
