Okay, here's the deal. I'll tell you everything honestly.
This whole situation is my fault. I forgot to add a clause about repeating turns in case of a disconnect. Therefore, Suris is technically right to not repeat his turns. Which is what he did after loading the save. And he was right, according to the rules. But not in a sportsmanlike way, in my opinion. Oh well. Sorry.
What are the options now? black_knight doesn't want to concede and demands that the match continue. Either with Vitalik on the test server, or with another test server player against Suris. Or, continue the match from the save without repeating turns. Another option is to think we won, and they think they won.
I'm in shock. This rule has always been in effect, even without being written down; it's more of an unwritten rule, dating back to the days of TOH. Put pressure on them; Lithuanians aren't Poles, they should acknowledge your rightness.
