Interesting Tolwyn. There have been confusing situations with docile enemies that have had plenty of fuel while I have been flying online with other group members and now I am wondering if there are two versions of 7.03 since you say that your 7.03 build did not have v1.2 of the Triggers.
Lucky me, I also found another way that the Triggers break the ntrk function today. I was working on a mission and I added a couple of "Message" triggers to keep some notes on the build and a 9.5 hour delay since I did not want them to show up during the mission. I ran it as a dogfight mission and when I tried to record a track I got the dreaded "track not saved" error even though the message was never displayed. I found out about this after flying for over three hours and right after I had dead sticked my P-38 in from 20,000 feet in for a really nice landing without breaking anything.
I removed those Message Triggers and flew the mission again and there were no issues with saving an ntrk.
