Zbrush stray zsphere, and how do i get rid of it ?

Zodd

I'm making a zsphere base mesh to sculpt on and i got this weird problem with a zsphere that is not connected to anything, is this something ordinary that i stumbled upon or is is a glitch?
Its really strange because ( im not a pro by any means ) i've done some digging around google and i learned that there are "magnet" spheres that are made by ALT+click-ing on a zsphere... so i thought maybe i accidentally made one ... nope it does not behave like that.
Is there a way to get rid of it? something like CTRL+SHIFT hide and DelHidden?? or am i stuck with remaking the model from scratch?
Also, this is a noob question, but maybe i can get one of the things sorted, i get this weird crunching when making adaptive skin... thought it was order in which i made zspheres but tried to recreate the problem and couldnt... maybe the stray zsphere is causing overall bad results on adaptive skin ???

bumpety bump, ended up redoing the zsphere skeleton and that fixed the adaptive skin, guess that stray sphere was influencing something still dont know what exactly or how it happened. So problem solved but still would be nice if anyone knows why or how did the zsphere detach itself... for future reference
