Inventory Loss

One of my tests that I use on my drop boxes is to copy the large list if notecards in my inventory into the contents of my dropbox. I've had a message pop up each time I attempt to do this: Inventory creation on in- world object failed. I'm assuming this has to do with inventory loss. Just about any information I have found on the Internet indicates that the item disappears in both their own inventory and the content of the prim. The message doesn't go into detail regarding what the name of the item was. In the mean time, I'm trying to identify the limit of how many items a prim can actually hold, and if it has an effect on the scripts performance. From Dedric Mauriac via bloghud.com
