Been working on this as I'm still learning the software and I changed something so I can't flatten this anymore. When I saved it last night I could flatten it but when I opened it this morning it had to rebuild to account for the changes I made. So apparently I made a change last night that I'm not sure of. I can unfold this piece by piece but I'd like to know what I did to make it not able to flatten anymore. Thanks
