The following steps reliably produce an exploding morph when I try them. I'm using 11.2 and ZB 2019. Fresh 11.2 install, no DSON.

1. Load La Femme and changed preview sub-div to 3.
2. Loaded pose Poser 11 Content->Univeral Poses->Action>Comic Book->Hero Action 1
3. Goz to ZB (Bake Morph + Material options selected)
4. Select the Inflat brush (Intensity 48, draw size 8)
5. Rotate view so viewing the back of the figure. Draw a continuous line from the back of the head, down the neck, to the left shoulder and down to the left heel.
6. Goz back to Poser and create new morph M1
7. Changed morph to 1
   I can normally see a vertex out of alignment at this point but may be necessary to repeat.

FYI As an experiement I used the Poser copy morph command to copy an exploding morph onto a new La Femme figure (not subject to Goz process) and that also had the explode problem but to a much lesser effect.
