Disconnected at this point, but when GM Fryslan checked the Zakum in question, it was back to full health (Room refreshed).
From what I was told ingame; Apperently the squad got kicked out as soon as 1 of their members dced. The squad leader if I understood right. When he dced they got the msg saying you will be warped out. Like the one you get when you defeat zakum. However, zakum was not killed yet, but had 40% hp left on the third body.
I'm not sure what happened with them, but I got disconnected and when I tried to log back in, I had to character fix myself. After that, I respawned at the long drop map before all the jumping maps before the Door of Zakum.
