Is anyone else on Xbox having trouble with the generators at the airport? I've fought my way in but no matter how many shots I pump into the generators nothing happens! I don't want to back up and try again because it's been tough. Anyone else experience this or have any suggestions?

My problem i had is that i blew them up but they'd still have the marker telling me to destroy it.

I had to wander around for like 5 minutes before it registered
