I can happen that a Object I want to move to a the Suit Inventory to a storage box dissapear once I release the mousebutton in the target field.

Every drag and drop and a doubleclick action at this Items I want to move ends in two things:
(1) the Item disappear in the target - "storage"
(2) the last empty (in my suit) non usable (broken frame) slot dissapear also

This is not always reproducible if I transfer items at the moment. The priority is "low" because after a reload all slots in the Inventory appears again - including the lost things!
