Sometimes (Yes an annoying sometimes bug) when i open the Ender chest, the items in there seems to be placed "off". Like between slots. When i go out of the chest my hotbar items has been "deleted". When i go back into the chest, my hotbar returns to normal. It's like it's "Pushing the slots" somehow.... I will post pictures to show the bug in a bit.

Before opening the chest.

Chest opened, notice that most of my hotbar dissapeared, and the items in the chest are slightly "off-slot".

Chest closed, hotbar emptied, and filled with items from inventory.

Chest opened 2nd time, al items are back....Some has switched places.
