Nimmy is correct.
I've just tested a simple Drag and Drop interaction with one drag object (caption) and one drag target (caption). I had a button on the following slide jump back to the start of the drag interaction slide and as long as I DON'T have the slide set to report to quiz, it is reset to a starting position when re-entering the slide. However, if I tick the box to have this interaction report to quiz, THEN it will not be reset if I re-enter the slide again.
