The berserk bug is quite unique... while the bug with a two-hex unit in tactical mode can be understood, the berserk bug clearly wasn't intended, either in the berserk spell itself or in the game as a whole. That's my personal opinion, although I'm sure there will be those who disagree.
The main point is: I personally believe that it shouldn't be used against opponents, precisely because the berserk spell, with this bug, turns into an incredibly powerful spell. I myself was caught in a battle with this bug, and I asked my opponent to replay – they agreed. I caught a couple of opponents doing the same, and I offered to replay.
The fact that Lebron and Dirty didn't want to replay is their personal decision. I think their behavior is wrong, although judging by the posts here, many support them. Considering the "mocking" of the opponent, and the fact that they are also the organizers of the tournament, I would have withdrawn from the tournament in Vova and Hellight's place.
I agree, considering the mocking... it's not right and it's not ethical. But in terms of the game, everything was normal... they were already in a less pleasant situation. If someone found and can use a spell, why shouldn't they apply it? Especially since Hell himself ended up there. Here, it's simply a defeat due to a lack of knowledge; the information is available. If Dirty and Lebron had prepared better, who should they blame? Moreover, these phrases about withdrawing are not serious at all... It's simply clear that there's resentment that such a powerful stack can be rarely assembled and upgraded, and then lost so easily... in any case, this will remain a lesson for them and for other players.
