The following post was recently made on the General forum: (http://forums.worldofwarcraft.com/thread.html?topicId=21723842445&sid=1).

    A fix was implemented earlier this morning and this issue should no longer be occurring. Thank you for your patience.

    There is an issue currently affecting the cross-realm dungeons when one player wins an item roll and then trades that item to another player who is from another realm. Under these circumstances, when leaving the instance the item may appear to be lost for some players. We expect this issue to be resolved as soon as possible, but want to remind players that they will need to have space available in the original backpack for the item to be returned when the resolution is complete.
