Game Crashes during Zana Rotation

I was doing a Zana Rotation and people in the party kept crashing.

The crashing seems to happen when someone starts the Zana daily mission. When that happens, 1 or 2 people from the party crash. It's not always the same person. I did not crash a single time, another player crashed 3 times. The people who's game crashes do NOT get the Reputation + Favour from completing the Zana daily mission.

This has been happening for the past 2-3 days at least (before then I was not doing rotations so I cannot tell).
