I've tried relogging, zoning to different instances, having my internet crash, and no matter what I do, I am always allied to every player on the map. This wouldn't be a problem if I wasn't flagged as an enemy to every one of them.
This issue is getting on my nerves and making this 'Fight in War Zones (0/15)' a very arduous task.
I'm happy that you guys have fixed the mission turn in parts, but for the love of Sulu... I'd love to actually be on someone's team for a change.
