Hi.
I also encountered this problem when leaving Iziz. I tried to resolve the problem in just about every way I could think of without success. I reloaded several times and it was always the same thing. Finally I reloaded a save game about 5 hours earlier when I was still at Dxun before I went to Isis. I can't really tell what it was I did differently but this time when I returned to Dxun there was no problems at all.
It seems to me that what you do in Iziz does not affect this bug but it is instead something that happens when you arrive there or something you do while at Dxun.
There are a few things I can recall that I did differently when I was at Dxun the second time around.
* I explored some more and found the droid control ship
* I did not save the lost mandalorian (I pressed the button )
* I finished two rounds in the battle circle (as opposed to just one the first time)
But it can't really se why this would make any difference and it might just be something random as well.
