Support Floors not respecting Z-Overides-XY

[AbeFM 35]

I have some complex models with curved/spherical areas where my PVA support should stick, and allow a tower to support features above.

(simplified test piece)

 

I had decent success, a recent print had all but one area supported correctly, so I made some changes hoping to perfect it:

 

I dropped Speed, Accel, and Jerk for Floors, increase floor density and changed the pattern to "lines"

 

And not a single support worked!

 

I'm not sure what's useful to provide but I'd sure love some advice. Using a CR-10s with a Chimera+ (i.e. two fixed independent extruders)

I see quite a gap on the support floors. I'll try to track this down.

It looks like XY-overides-Z is only for the tops, not the bottoms, and ruining the prints.
