I was working that same hex at that time, as well as GDA-Doc I think. I was in a drone boat, precisely to run fast missions.
Whenever I faced a klink AI, the news gave an item "hex 3,22 attacked by Klingons" after mission ended. Similarly when I faced orion AI, the news fingered the orions. This is all as it should be.
During the time in question, I didn't run into any live players at this hex. Coincidence. I was able to run very fast missions. Hence the result. My guess is, there was nothing wrong with the server.
