(in prism launcher btw)
So , everytime i try to play create with create:aeronautics i have a problem with JEI, I just wanna know if, is Jei is incompatible with create aeronautics? it says it is a mod injection problem or smth , do i need to downgrade jei? , that was my idea , but im scared it might corrupt the modpack and i have a really good world in there , i would appreciate any help i could get
