I am currently playing the most updated versiojn (1.12.2) for the Weather2: Localized Weather and Storm Fronts mod and I've notice (since I made a town in the desert) that no sandstorms are spawning and I read about a coroutil being wrong so I downloaded the coroutil-1.12.1-1.2.2, and starting getting a sandstromFogAmount message everytime my game crashed. I've also noticed the weather radar isn't working properly.

Can anyone help?

Dont mix release builds with beta builds, curse is dumb about it and will download release coroutil with beta weather, verify it yourself.
