problem with Z0 and m6

[kjetil]

I have trouble with that when I need to reference curretn as workpiece. I lower the bit to the material surface and press z0. then I press reference curretn as workpiece. then it goes to the probe and when it hits the probe it just goes further down.
But if I set z0 higher up and do the same procedure then the probing goes fine and it goes back to perfect z0.

I'm in mobile probe mode and the probe is working properly I've tested.

just a few days ago everything was fine.
can this be a bug?
