I am glad someone else has noticed this. I thought my Fleetmate and I were doing something wrong.
Diplomat not being hit - Doesn't count
Red Alert off and Diplomat not being hit - Doesn't Count
Tag Diplomat between spawns - Counts sometimes and other times not.
Tag Diplomat that has "moved" previously - Doesn't count
What the heck? What is the magic way to get them to count? It is making my Fleetmate want to quick the grind for Fleet marks all together as this keeps getting worse. I am almost desperate enough to ask the PUG to NOT get diplomats until we have cleared group 9/10 and Mook.
