The default PID gains are messed up

Edit by Pedro: P10 I0 D25 by default in the capsules, the inputs go insane with that derivative.
Original title: Command Capsule Shake/vibration
Capsule shakes and veers off heading when detached from booster segment. Stops shaking and will hold its attitude when heading is unlocked or power is turned off. As soon as heading is locked or is power is turned back on the shaking and veering off heading starts again. It does the same with every capsule. I've restarted the game and my computer. I can recreate it every way I think of. Can't think of what could be causing it.
