Hello,

Yesterday during CFR #429, I saw something magical thing happened to me.

Just before the end of contest, somehow my problem D was submitted and accepted!!!! ****

I already gave up the problem D and E due to the hardness (as usually), and I was trying to fix my hacked problem B. I think someone's submission was counted to mine, but at the end system judged that I cheated and copied :( Is there someone else who have seen this issue? I hope the admin fill fix it, and rejudge my submission.
