HOLLY CRAP I MADE A BIG MISTAKE. I MAY HAVE LOST HOURS OF DETAILED WORK.

Ok here's the situation I am facing here.

I am adjusting these poly's before I copy over a face half to the other side. I hit some key that turned all the verts yellow. Not understanding what I did so I save it and closed the file. Re-opend it and now all of my polygons are separate from one another, dammmmmmmmmmmmmmmm, sorry but I lost 3 dys of work if i have to rebuild the entire thing over again.

PLEASE tell me there's a function in Maya where I can select all the faces and attached the verts without having to rebuild this all over again.

Forgive my tune but why oh why did I not save in sections. I feel so stupid

Thanks in advance
