I notice that when i use Optifine, or any other mod for that fact, clouds disappear, The tornadoes and hurricanes still function properly, I just don't see them. So i get blown in the air from something i can't see! Please Help, If you need a screenshot, i will get you one :)

It happens with many big mods, a few like iron chests, storage drawers, jei, inventory tweaks, etc... are able to work with this mod.

well ive got a small mod pack and found journeymaps and and buildcraft so fa casuse the issue and im running thaumcraft, tinkers construct, bibliocraft, immersive engineering,projecte ,optifine ,jei , and the stoarage drawers and a few others and it works fine well other then the storms don,t form the actualy tornado funnels but that was happening with the mod by its self

I only have the mod Factorization with this...

can i get a screenshot if you able to still

I have quite a few mods for me not much but enough like to make a thaumcraft pack in 1.89 and i get the same thing. it darkens the sky and when you leave the area it calm and quite but still happens. also when i try to do the overcast mod and use vinilla rain and stuff the lighting seems to flicker and the sky seems to have the clouds fliker from clear to what it looks like when it rains alot. and i do have optifine but it was happening before i added optifine
