Remember the best possible thing you could do is lock each 2hr as it appears, first try aka every time it 2hrs from the very start locking 1 after another. Nothing is wrong with locking Call Wyvern right off the bat unless you accidentally kill all 3 wynavs. What you want to do is have the kiter grab 1 while the other 2 are killed instantly. The kiter takes it to low HP % ~5% so Mijin has no chance of killing them, you then proceed to lock 2hr after 2hr.
I can't explain what happened in your situation because I obviously truly have no idea, but the fact is we have done the exact same thing by holding 1 wynav the entire time, they don't just die. That is the best way to do it.
