What happened?

A flickering effect is being created when moving in an area that produces the fog effect from this mod.

Reproduce steps

1. Install Alex's Caves 1.0.4, vampirism 1.9.3 and required dependencies.
2. Travel or teleport to location that uses the fog (This includes a village with an active totem or the vampire forest)
3. Move the player character around in the environment to notice the flickering of the fog effect.

As quick workaround you can set the biome_sky_fog_overrides config option in the alexscaves client config to false

AlexModGuy/AlexsCaves#109

Alexs Caves has some logic to calculate the fog which no longer works correctly when other mods use fog.
