Or it may just be the rapid change in maneuverability that is tricking you
No, I'm
pretty sure it isn't. Fire up a Falcon and pit it against a Mule. Hold fire. Turn the Falcon around, and as the Salamander missile is coming, turn on Jets. Let it hit a Jet (and only a jet) and then wait until Jets turn off. Don't move in the meanwhile
Your Falcon should be very sluggish on turning and/or it should be turning on it's own, even with only the main engines on. I just tested it. And I'm pretty sure it's not just me.
Also: What is the deal with this topic? First it was in Announcements, and now its a sticky bug?
It was originally in the announcement thread for 53.1a because I thought it was okay, but Archduke Astro didn't think so. So he moved it here. For some reason, that left a spare thread there.
