Just as it says. However about a week ago when I first started the game in .25 everything was working as it should. Now, no matter what I'm flying, the craft will just spin and not maintain a heading whatsoever. Doesn't matter if I'm in the Kerbin atmosphere or out in space. Thought it was cause I was running a rocket with no thrust vectoring; got to space, jettisoned that stage and was down to just the command module (no other parts), and still, it just spins, won't keep a heading. SAS tab is clearly lit, tried resetting it with the 'f' key. Nope, won't maintain a heading at all. Also, I was having no issues with this in career mode about a week ago. Well, I failed in career mode and started over today and now I'm having these problems. Haven't tried sandbox mode or science mode. Forgot to mention I'm running the 64 bit version of KSP. Any suggestions?
