I don't know if this is intentional or just an oversight, but I was just looking at the new generation in the most recent 21w42a snapshot and came across a frozen ocean biome with a lava stream pouring out of a glacier as if it were a mountain. The seed is [-4061070154301603804] and the coordinate location is -487 72 693. Just curious to know if these have been a feature that I've missed. Thanks.
