Short description of the issue and how to reproduce (is it random / always happens / side conditions ?)

Middle-clicking an item frame that contains an item, in creative mode, with an empty inventory (thus getting the item), triggers ImpossibleHit when an item fram containing an item is subsequently hit.

Put an item in an item frame.
Enter creative.
Clear your inventory.
Middle-click the item in the item frame to get it on your hotbar.
Hit the item to remove the item from the item frame.
Instead of the item being removed from the item frame, the message "failed ImpossibleHit: tried to hit an entity while performing another action (Tags: inventoryopen)" is shown.

ImpossibleHit triggers if hitting any other item frame with an item as well (once the item has been middle-clicked), but it doesn't trigger if hitting an empty item frame.
Middle-clicking an empty item frame does not trigger ImpossibleHit at all.

Have you made any (noteworthy) changes to the default configuration of NCP?

No

Do you run any other special plugins that affect game mechanics next to NC+ (skills, machines, adding/changing blocks, other anti-cheating)?

mcMMO, CraftBook, ImageFrame
