If I select a mesh strip and adjust the count, the hair disappears and I can't get it back

Actually it doesn't disappear. The wig becomes huge and moves into z and rotates.

Ok thanks. Turning off ground strands fixed it. Sorry to be bugging with these little problems. I haven't used Ornatrix for a long time and I'm getting re-acquainted with it.

Actually, that's what I meant. I detched and reattached.

Is it a good practice to detach roots whenever I need to modify something? I'm finding that the hair will do weird things if I don't. Sometimes the width becomes really thick and I have to set "change width" to a really low value to get the hairs thin enough.

I'm finding that the clump operator causes most the problems. I'll save the scene and when I re=open it, the hair is all messed up. If I delete clumps and save the scene, it re-opens the same way I left it.

Is there a perfect order to put the operators in the stack? There's lots of times I have to rebuild my Ornatrix hair because doing some things will cause the hair to go haywire, whether its the width getting huge, or the frizz values changing..and the value itself doesn't change, but the way its interpreted changes. 

In the pic I attached, is that the correct way to stack the operators?
