You mean it works at 1.29, then it doesn't at 1.31 ?
Officially, because you need the extra speed more than you need the fighting power. Unofficially - because we wanted to give you one last farewell mission in the Stiletto. Sorry ."First Encounters" is so broken.
I have easily at least a dozen Rapiers. Why is my wing flying Stilettos? This makes the mission just far too frustrating.
I had to go to Rookie to beat it. I felt like a failure. :<
