Re: Can't order Upgrade Parts

I can no longer purchase upgrade parts by clicking on a computer.  I used to be able to purchase upgrade parts by clicking the computer, selecting order and then upgrade parts.  That option no longer appears on the computer.  Since purchasing the latest game pack, I have been able to purchase upgrade parts.  Since the latest update, that option has disappeared from the menu.  Please advise if there is another way to obtain upgrade parts.  PC, NO CUSTOM CONTENT.
