One of the items that you can make in the game is bugged. The dimensional casket is a light blue box that is supposed to allow you to trade with any NPC from any distance. It uses a menu to let you choose which NPC you want to trade with. The bug happens when you select an NPC to trade with, it says that you should press escape to stop dialing, which I assume would mean that it stops the trade with the selected NPC and allows you to choose another, but when I press escape it closes the trade menu. When I open it up again the dial menu appears for 1-2 frames and then automatically goes back to the trade menu for the NPC previously selected.
