affects beta 1.14.2.50 as well (the latest 12/19/2019 beta)
please fix the Bedrock roofed forest grass color bug, mojang/microsoft.
Also while we're at it, Birch Forest M/Birch Forest Hills M and Savanna M/Savanna Plateau M have the same grass color problem Instead being the correct biome color, they have the same incorrect green color like the roofed forest and roofed forest M.
The wiki called it a feature, they don't know it's a bug.
Still an issue in 1.16.0.66 beta. Attempting to change the colormap to the correct color will also cause normal forest grass to appear as roofed forest grass.
Confirmed on Samsung Galaxy Note 5. Android 5.1.1 Version: 0.14.0 Beta 3
