i highly doubt AK MX would be to blame. They would state the case that even if they needed to put the pressurisation Auto system on MEL that the plug could have fallen off even on AUTO mode. Would have taken enough cycles. Not armchair QBing how the crew handled the manual pressurising system but who knows.
