DynamicSurroundings-1.12.2-3.6.1.0.jar

Not a crash, but when Harvest Festival is installed, Dynamic Surroundings weather effects don't work at all (Rain Puddle Splash, Duststorms and alike). i'm assuming your mod handles its own weather rendering? There aren't any config options currently on either mod to fix it.

Thanks in advance!
