I was playing Clone Campaigns, campaign #1 ("Confederacy") and the mission was #5 "Opening The Wound".
The mission was to basically escort the droid with the Decimator codes, to the Decimator Facility for deciphering.
But there should have been a mission objective to keep the Decimator Facility safe (at least one of them), because I destroyed them by accident yet the mission finished successfully.
This didn't make much sense because the whole point of the mission was to bring the droid there to access the newly stolen Decimator technology to put it to good use. The Confederacy wanted to use this new technology against the Republic.
Count Dooku was depending on General Tann (the player) to gain access to the technology, but if you "accidentally" blow it all up, he's still very happy in the post briefing, as if you went through the mission as planned (ie delivered the droid).
Small thing, but just thought I'd mention it =).
i know the one you mean. You do need to watch out for it. I think once u (Sev'Rance Tann) gets close enough, it will change to your colour
