Stage 5 of the John Van Caneghem Tournament

Please clarify - what time on the 20th does the official submission period for tournament results end (at 24:00 on the night of the 20th to the 21st)?

Correct.

Only the replay of the battle with the ghost squad guarding the passage to the obelisks?

If you fought against another player, send those replays as well... If not, only the replay with the squad guarding the passage to the obelisks.

So, there are three mandatory replays that are sent to the judge, plus the last save file, right?

That's correct. And it would be better to ask such questions in a private message... ;) in my opinion, the answers to them are obvious:)

I sent the save file (for the umpteenth time), did it arrive or not?

Congratulations! The save file arrived:)
Also, the save file from Alexxxok arrived...

There is very little time left:)... Play and win:)
