Kevin_A I have been pestering them now for months to put it back.
Completely random "techincal" activities over there.
When ASIAIR first started ueing PHD2 for auto guiding, it was using a 0.2 pixel MinMo.
When I acquired my first RST-135, I wrote and told Sam that a Harmonic drive that has no backlash needs smaller MinMo to work well. It took at least two years of pleading (and only after they had started "designing" the ZWO mounts) that they finally relented, and changed it to 0.1 pixel; presumably, as you found out, 0.2 pixels is a disaster for these gears.
Now some random person with no Control Theory background decided to change it back to 0.2 pixels again in an early TestFlight.
Finally, they appear to now allow 0.1 pixel again.
What a zoo.
