I thought the product inventory is dependent to the region, so i claimed all items (celebration gifts, and additional package) on another region (europe west) where my main is (europe central) accidentally.
Also somehow I did not see those pacakages on europe central, they just appeared when i join europe west, otherwise I would claimed them already on europe central.
AG can do nothing, like with pretty much everything else. They can not even transfer items from one server to another in the same region like you would expect from a mmorpg support.
