Diggable treasures in the deep mine?

It's kind of weird these spots can spawn in, but you can't seem dig them up underground. Isn't it? Treasures aren't actually gettable underground, but the x marks the spot can show up underground in spots that are unearthed. Say you mine a rock, a placeable tile, or a wall. Those x spots can then show up when they normally don't. It's like a bug really.

It is an old glitch. X does not mark the spot in mines so no need to bring a shovel with you. It is possible that sometimes trash bins spawn in the mines but those are already above the ground so you can just break them open.
