After beating wall of flesh, the v-shaped underground hallow and crimson spawned in an unfortunate way, leaving very little clean ground above the hallowed branch for the spawn town. Now I do know how to isolate the evil biomes, but I was wondering how the spreading worked. I noticed that the underground hallow BIOME is slightly larger that the area of converted blocks itself, so I wondered if spreading can go as long as nonconverted blocks are in the underground hallow biome, or if spreading goes only block to block.
