I was saying that for some reason the darlington seemed to fail shorted. At that point, the mosfet could do whatever it wanted, and the gate of the mosfet could be kept low by the overcurrent circuit, but it wouldn't have any affect on the darlington being a dead short. The question is why would the darlington fail shorted before the current got too high, because as long as the darlington was working, it would have been disabled by the overcurrent circuit if the current got too high.
