I sp mode, when i pick up bodies, I can't put 'em down again. ive tried evry thing. Pressing enter, space etc. Could you please tell me how to put 'em down!

 Reply soon!!

ive had this problem, its due to either your card being too old (doubtful) or actual memory you got on hard drive. You may also have probs pressing other buttons and not gettin a response, like special weapon keys or crouch (i solved the prob my clearing alot of free space on my drive).

I don't know if this is the same thing or not, but there is a serious in-game limitation on where you can put the body down.  Namely you need a lot of empty space in front of you before you can drop the body.  I've made a mistake of picking up the body and being unable to drop it because the game doesn't think there is enough room to drop it.  This happened to me on the mansion level in a house with two caged dogs.  I killed the guard there and was unable to drop his corpse anywhere in that house after picking it up.
