Okey.
History behaves a little wierd with the loopsplit nodes,
when u delete history the nodes get disconected from
the shape BUT the still remain, they are not erased, I
noted that if u have a maya standart node like say bevel
at the END of the history it does delete all the nodes
when u delete history, this works but not always, works
best if U freeze transforms first, wierd.
I'm concerned about those nodes not been deleted
cause they can cause some trouble.
