In the Frozen Ocean and Deep Frozen Ocean biomes that have already been loaded in privious versions(1.21.??? half a year ago), there are chunks where stones are produced on the surface instead of water or ice. Some of the chunks(Stony Ocean I’ll call) have icebergs but made of stones. As in the general subsurface, in addition to stone, masses of gravel, coal ores, etc. are also produced. Sometimes Glow Squids spawn near them. But within the Stony Ocean itself, there is no water as there should be, but instead it is filled with air, so a wall of water is formed at the boundary of the chunk.
The phenomenon only occurs in locations that have been previously loaded (in order to create the map). Otherwise, it is the same Frozen Ocean biome as in the latest update.
Thank you
