A-B line incorrect
If I have a mower attached and want to mow with GPS, I set the A-B line, as soon as I activate GPS and drive, the angle of the A-B line changes by about 5-10 degrees and the tractor drives a wrong track.

To Reproduce
Steps to reproduce the behavior:

1. Set A-B line.
2. Activate automatic guidance.
3. Angle of A-B line changes about 5-10 degrees.

Expected behavior
The angle of the AB line changes by about 5-10 degrees and the tractor drives across the field or meadow at the wrong angle.

A clear and concise description of what you expected to happen.
I actually expected the tractor to drive the A-B line that I had previously set.

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
tested on different maps and without mods

Please check the option „snap terrain angle“ („An Bodenwinkeln ausrichten“ in german) on the gps settings screen. It defaults to „on“.
Turn it off an set your A-B line again.
It should then behave as you described in your expected behaviour.
