So, weird one here, but for whatever reason, using this mod causes an immediate Fatal Error when loading into the Arctic Biome on Genesis Part 1. Stripped all my mods to test, and can confirm it's this mod, and it's only the Genesis Arctic biome. Everywhere else? Not a problem. Other Genesis biomes are fine, as are arctic regions on the other maps. Only started sometime recently, so no clue what could be the cause.
