@md_5 Sorry to bother you, when you have an item you're placing in an inventory and you even ever so slightly move your mouse, it should trigger InventoryDragEvent right? Has this changed, I see it mentioned in the javadoc, but it doesn't seem to trigger the event in some situations. If you drag one item (it seems fine when it is 2 or more) in same slot then you have this bug(?), But if you drag it across multiple fields then its fine. At same time click event ignores this action as player did dragged item just not across multiple fields, it seems. This only a bug with single item in your hand while performing drag in same field, everything else seems to be fine I've asked around but so far the response from people that know more about this than me has been 'yeah, I do not know.. seems like that isnt working or something'.
