In the PC version, I managed to get two objects to permanently float in the air (shadow is 1/2 inch below them), and I cannot do anything with them.  The hand does not change when hovered over them.  Unfortunately, one of them is the notebook/Almanac Alchemica, so I can't carry it around anymore.  I can still add pages to it by dropping them on the floating book and I can read it by standing close to it, but I cannot grab it or put it in my bag.  Is there anyway to fix this without restarting the game?

Also, I blew up many areas that revealed trap doors, but I have been unable to figure out what to do with those trap doors, I am unable to open them with my pointer/hand like I did with an earlier trap door, that was the only one I could open.

Thanks for any help anyone can provide!
