Well I saw this coming and I was afraid this was going to happen. VIGILANCE ended and it was not successful. The problem that I noticed was definitely the drones not showing up as often as needed to success this mission. During my playthroughs, I only got the drones to show up about 60% of the total time I was playing, maybe even less. And sorry to say, this could have been avoided if Bioware programmed these drone escorts to show more often. But it seemed like they were showing even less, so it was a matter of us to play lots and lots of games until they actually did.
This means that on the next N7 Weekend, we will have a Special Condition added as punishment for not finishing this N7 Weekend successfully. And it sucks cause it felt like a huge handicap.
Well better next time guys!
