Nether biomes in safezones (AFK world, boss arena, possibly dungeons)

To set these areas to "neutral" these areas were set to "nether wastes" biomes. There are at least two downsides to this 1. The sky gets a reddish tint 2. You can hear nether ambience sounds The spawn warzone is mainly made of 3 biomes, and is mostly if not entirely neutral so far as I know - River, Beach, and Flower Forest. I think these may all be neutral biomes, but River I am pretty much certain is neutral. Perhaps consider setting these areas to "River" instead of "Nether Wastes", using the Faction map (/f map) to confirm that this is indeed a neutral biome.
