Large, frozen and deep frozen oceans are occurring much more often than normal. While biome generation has changed, this biome is much more frequent, possibly due to the new mountain biomes which are almost always accompanied by cold type biomes, prompting frozen and deep frozen oceans to generate. With the added bug of frozen oceans and deep frozen oceans covering the surface water, entire oceans can be covered in ice. While icebergs still spawn, they are in the layer of ice, appearing as if the biome is a ice spikes variant with hills instead of spikes and only ice.
