Hi Rainer, I haven't seen the disappearing-sphere problem before.
If you have an example model that has this problem, can you please send it to me at moi@moi3d.com?
It probably won't be fixed in v2 automatically, I'll probably need to see an example and debug it before it will get fixed.
Also, when you cut a pattern, make sure not to have self-intersecting curves (like something with little curly-cue loops in it) as your cutting curves, those will tend to cause problems like you are describing.
