Guys, cut it out, especially with the threats involving fists. It looks like I'll have to hire security just in case :D

I talked to Helen, here's the translation: he had two saves, one at the beginning of his turn, and another after two quick battles. They loaded from his save because Kostya didn't have a save from work. Helen loaded the save from the beginning of the turn to remember, and then he loaded the second save and started playing from there. If nothing else happened, then this isn't a violation of the rules.

1. We were playing with his auto-save, and at that moment, his timer was 0. What is this nonsense about "2 quick battles"? It's a shame I didn't have time to take screenshots with the save dates; we still need to teach such players a lesson. So, he loads his auto-save, and then Gunnar, who was standing in an open field with a Troglodyte (and clearly hadn't had a chance to move), runs away from his starting position. I ask him in ICQ - what are you doing? Why aren't you passing the turn? He says he's "remembering." I think, "Wow, you already took your turn; do you really think I've forgotten everything in the last 1.5 months?" Whatever, let's move on.

2. After 10 minutes, given for "remembering," he simply exits, saying he's "remembered" and is now loading (when asked if he couldn't have remembered while I was taking my turn, he replies, "I didn't understand"). He loads - the timer is 6 minutes, Gunnar is again with the Troglodyte, and then the movement begins... I had to leave urgently, I come back, take my turn, and review his turn - I realize that the turn was simply replayed, but I have no proof in the form of screenshots or my own saves; I was just taken for a fool. Okay, I think, let's finish the game like this; the game itself was very interesting. I managed to get out of a difficult situation, survive until the late game, and put up a fight, but in the end, two Logisticians set up a simple checkmate in 3 moves.

3. I simply write to the person, "Thank you for the game," but I note that I really didn't like those save manipulations. The person continues to play dumb and writes "???".

4. I delete him from ICQ without further conversation. It's simple. Let him enjoy his great victory.
