My old Max patch was at hand so I looked there and I have Track Up on 68 there
Up Numerically or Topographically (North) ?
Afaicr it all worked as it should - because, check everything
Now whether there’s a glitch since or MK2 issue I don’t know
But I guess the manual tallied with my experience a few years back fwiw
I’ll move to dedicated bugs discussion thread shortly
