When ever I move gold items around in my inventory or chests or any containers while the gold item is moving to the slot I'm moving it to it will iron while its moving. Sorry if it's hard to see on the video can't show it very well in such a short amount of time. I just found even more items that the textures glitch for. I took screen shots of what items do this. But theres one that I really want to point out the conduit has no animation or anything when you move it
