sry maybe I should have described this a little better. On the pre nge servers a player that has a placed a cantina in a city can drop items like a basket and move it up and on the bar counter in the players cantina. On the nge servers the item when it is moved to try to position it on the bar counter gets a invalid location message. I think there must be some kind of collision in place that prevents any item to be move into this area. The same collision seems to be in affect on the shelves on the wall behind the bar.
Then it's very possible, the Pre-NGE servers have updated the hitboxes on their servers, so they can do that. Where objects can be placed/moved to in a building is defined by the server itself. (I was talking about the wrong ones in the first place)
I don't think the "Source NGE" servers have quite figured out how to fix that, yet, since they'd have to dig though SOE's broken code just to find all the 5-10 (new and old) different ways it's defined.
