Actually, I only used that bug in my last 25 or 30 missions, and the majority of the missions I got from it were broken anyway.

I did get to a point where I stopped bothering with missions if they were combat oriented, If I went into one and it said Secure the Sector, I'd just leave and move on to the next one.

Edit: When I say majority, I mean it. The last time it actually popped up nine times, and 8 of them were broken Aid the Planet missions.
