Seed 306959825 X-2560 Z-300, X-560 Z-2455

Intended Supposed to be: Roofed Forest M supposed to generate roofed forest trees, some tall grass, have dark green grass color.

Instead: it is a empty biome with zero foliage and only light green grass.

I attached a biome map of the same seed, you can see one roofed forest M biome in the direct west and north in the map. The biome terrain image is the same biome. The other roofed forest M biome is next to the Savanna M and I included it too. It is not a plains biome with the grass color being off.

 

Reproduce: Find a seed with a roofed forest M biome, go into it (create NEW world in the MCPE 1.5.0.10), then view the technical biome, you'll see roofed forest M and no foliage. You can use my seed above.
