Losing z-axis zero when hitting stop&RTZ in UGS

I’ve never seen this before, but I just started using touch base so maybe it’s related to that. When my carve is running in UGS (nightly version, 12/7, 1.1f firmware) and I hit the square red button, it stops as you would expect. The XYZ homes are correct. I raise the Z axis to clear my workpiece and then when I hit , it slews back to work home, but the z-home gets reset to the same number each time… 25, I think. It resets before it slews.

This version never did it before when I was manually setting the z-axis with a piece of paper. I’m using Phil’s touch plate macro but with a change of thickness of my touch plate. Any ideas? Nothing in my PP has changed.
