Ornatrix Maya: collapse stack not identical

Hiya, I have a complex ornatrix stack, when I collapse it, the groom changes. I can't be certain what exactly is changing, but is it normal to expect any changes on collapse?

EPHERE	It's likely that just the viewport preview changes, the final rendered hair should be the same. The hair Hair from Guides previews hair might be a little different from Baked Guides node, so the positions of hairs may change a bit after collapsing. However, if you render the hair you shouldn't see a difference. Marsel Khadiyev (Software Developer, EPHERE Inc.)
