So to be clear...

If you time it correctly, and plug in USB and then flight battery, sometimes it will start up correctly the very first time?

What is the git hash of the version of next you are running?  If you do "git log" you will see it at the top line of the page.

Yes you are right, if I do it direct after one another it startsup good everytime.
What I did is increase the time between USB and battery in small steps and found out that around 1 to 1,5 sec it starts to fail to recognize the AuxMag.

I did a git log and these are the first lines. Is this what you need?

You need to find the mag orientation.

Is the mag facing back compared to onboard mag ?
Do you have a special virtual attitude for your board ?

Both mag alarms are green ?

Sadly i cannot reproduce this issue, whether using a HMC5983 or HMC5883 chip.
Both works fine without any error.
Try redo wiring, more short and wires twisted just to be sure.

Please post a good macro picture from your GPS/mag chip

Could you test my exe to see if you get this problem?
