I can understand wanting to keep the integrity of the fight, but something is fishy. So as Limit is progressing on the boss, Method decides to run heroic splits for better gear. Then Limit has a pull where for whatever reason, bug, glitch, improper mechanics, cause Limit to go to 25% and look in great shape to get world first. Blizzard hits the button to end the attempt.
I know this is tinfoil hat, but if someone at blizzard told someone at Method, that the encounter is bugged, dont bother attempting.
In a race this close, it seems odd for Method to go for gear over attempts. Unless they know the encounter wont be beat, but they can watch stats while they get an advantage. Meanwhile Limit keeps attempting, not knowing Blizzard wont let them get the kill till they “Hotfix it” with the reset.
