Emerald Pots generating inside terrain.

Whilst exploring the world I have discovered various Emerald Pots “buried” in the ground or inserted in a wall. I believe this to be a bug as they are unbreakable due to being outside of the player’s reach.

First encounter was in The Sift where some pots were inserted into a wall and I could only break them with TNT. A more recent encounter was found by just exploring the overworld. Buried pots are spawning where I have seen regular pots in previous sessions.
