Death causes group disbands
 

I just started playing on project 1999. I saw some similar posts to this one when I searched. For my brother and me, every time one of us dies, our group gets disbanded. Also zoning causes the group to disband, which I have seen in another thread.

Been happening a lot in HHK groups as well. Like the OP said, soon as somebody dies, they are booted from the group.

This does not seem to happen... (or at least not as often) on raids (ie: Sky, Hate).
