Oolite Bulletins

I just spent about 1 RL hour on a local hero mission where the bad guys never showed up. I flew back and forth between the N and the W buoys again and again and nobody ever showed up. The mission dude got pissed that I kept docking for fuel (lots of injector usage) and said the mission failed. I even flew all the way around the planet looking for them but could never find them. Does anybody know what's going on?

I remember one like that.
After the first tiking off from the guy at the station I didn't bother going back there for fuel went to the sun. Kept going up and down the space lanes still no sign. I think I might have witchspaced to a nearby system fueled from the sun and jumped back and they hit me right near the station.
