Many of you helped me with ideas on the "exploding hair" issues. Now I need ideas on why a hair group "sheds" all over the place.

It seem to happen "whenever" and not with the group being worked on at the moment. Therefor it feels a bit scary if it will happen to any group at any time. If you know what I mean.
I can isolate which hair group it is and if I delete it and redo it the problem is gone. But the thing is I would like to have an idea of why it happens in the first place.

Any suggestions are welcome.
