Broken: 2.8 24.02.2019
How to reproduce:
Add 2 metaballs, change resolution and threshold.
Deselect. Add another one meta. It will appear with default settings.
Change it`s settings a little. Delete it.
Setting will drop to family.
p.s. The same bug at 2.79b: new meta appears with default settings.
Metaballs is great and powerfull, but sadly bugged…
