Thank you, I experienced it once an thought I was going crazy! We were flying with your controls when it happened.

Looked like an interpolation bug as the compass smoothly interpolated from 358° to 359° (clockwise), and then from 359° to 0° (backwards/counter clockwise).

Managed to reproduce the bug reliably:

On the ground, spin the aircraft clockwise for 720 degrees. North has to be passed at least twice for it to occur.
The second time it passes from 359 degrees to 1 degrees, it spins counterclockwise. The spin rate seems to pick up with every subseqent spin.

I'm looking at the code right now!
