All of (GMT) day today, for my Serco character, all ships in BS sectors during the missions show red on the radar. Only when the mission ends (one side retreats), Serco ships suddenly show as green. Ships in Geira show as green, as usual - this only affects BS sectors. I played small, medium and large missions.

Is TCS installed?

What's TCS?

Anyway, the factions were displaying correctly for me on the test server and on the first day after the release of 1.8.72.

EDIT: Just checked, all ships show correctly on the radar now.

TCS does not fix it...that was my first thought too.
