Working on a tech support request. Got an email with an error message that was being displayed. I spent some time trying to figure out what was going on. I found out that a corporation had a number of my cart favorite buttons and they must have asked for those buttons to be copied over to another corporation (they own both corporations). It looks like the buttons were copied over but none of the key id numbers were updated for the new corporation. So, it looks like the new corporation has a bunch of my cart favorite buttons (quick add to cart and quick look-up buttons) but the buttons point to items in the original corporation. I sent an email with my findings out to the rep/consultant and to a number of developers to keep them filled in.
