As for skipping a turn, everything was done under the control of Yar (the organizer), since he didn't stop the game or force Goma to replay the turn differently, it means it was done correctly.
No, it all happened very quickly, and I didn't immediately understand what had happened, around the 14th hour of the broadcast)

"loading a battle save doesn't fix the crash at the end of the turn."
It might fix it, usually that's how it's done, but on THAT day, it didn't help.)
