No no... TO put something or you press and hold R, with the equipped item in hands or you press R and Right-click (before the "hold a button completes").
Soo: With the item in hands: R and less than a sec right-click
Okay so there just is no more ALT+R to place items down that you're holding anymore. You have to use the precision placement tool now?
Holding the Item: Hold "R" looking to where you wanna put.
