Good evening… (good?)
There were difficulties with the round, for which I apologize. During the contest I was able to partially locate the troubles, I hope we’ll fix them soon. Apparently, there were two troubles: 1) site didn’t respond, 2) for hacking attempts occurred inappropriate message that hacking is already taken. We will investigate it. Thank you for your patience.
So we decided to do it unrated.
I added work to the next round, the more so because I'm going to be its author:)
