We have made a change to the inventory system when it is full. If you receive an item, a new window will now be opened where you can extract it.
This will for instance apply if you complete a mission without sufficient room available. Please note that the window will work as the loot view you open after killing a mob. The items will not be considered yours, until you make room for them and move them to your inventory.
If you decide to close the window, the items will be lost.
