"you cannot leave items here" when dbl clicking to loot item

2. This happens 1 out of 5 to 10 attempts to dbl click an item to collect it from a corpse
3. Not a blocker - you can drag and drop the item to your paper doll
4. See #4
5. After you kill something, dbl click the item to collect. Occasionally (1 out of 5 of 10 times) the item will not collect and you will get the message box "you cannot leave items here" and the item will shift in the corpse. Repeated attempts will continue to shift the item around in the coffin randomly.

 

I have the same problem and have had it for many releases. Usually I get that message on the last item in the container.
