Taken at the latest Bedrock Beta 0.16.0.63.

I created a new world in the Nether and traveled around different biomes. But then the Basalt Deltas became different, like its now mostly composed of netherrack, especially the ceiling (which is really disappointing) If this is actually updated, I just wanna say the original basalt delta is  perfect. The ominous, grayish palette is already amazing but now having mostly composed of netherrack just looks almost like the regular Nether Wastes. It already lessened the hype. But I don't know, maybe this is a bug? I'm pretty sure you also don't agree with Basalt Deltas looking like these right? I tried to travel at different basalt delta biomes to see any changes but all of it just looks the same, now mostly composed of Netherrack. The pictures were taken at different basalt biomes.
