Bug in Campaign 3

[Wydom@ker]

I have come across a bug in the mission I am currently trying to do...now I can not complete it.

This is the kill the Sithrak Starbase in the Jinook system. I've been at this for hours and have bearly scratched the thing - its shields and armor are enormous and as for the damned weapons it uses...I have to get my weapons fixed after every attack run. I am now using their weapons against them after clearing the system of Sithrak ships.

This is not the problem/bug however. I left the system to seek out better shields,armor and weapons for my poor little cruiser - Abbidon Series 2 Cruiser Mark 3 Plus. While out of the system I saved and exited the game to get some zzz
Returning to the game this morning, the Sithrak ships are back in the Jinook system but the Sithrak Starbase is GONE and I know I did not kill it, and the Terran fleet certainly didn't - it couldn't even get past the Sithrak Battleships

So, how do I now finish this mission with no target to kill...
