I did pick up these pages in the Mechancial Age, but somewhere along the way they disapeared before I had a chance to place them where they need to go. It's been some weeks since I played this las t, so I MIGHT have placed them inadvertenly where they need to go, but I have no way of telling if I did. I doubt I can go back to the Mechanical Age and start over. Is there an option that allows you store these pages once you retrieve them, outside of them being displayed in your curser "hand?"
As I remember things, you could only have one page at a time. So if you had a 'red' and picked up a 'blue' the red would be put back. You need to go get a color and bring it back to the library and put it in a book, then go get the other color and bring it back to the library. If you found them once you won't be redoing the entire area, just go back and pick up the page you want.
