Seems that you cant use OptiFabric and LambdaControls together.

Error msg:

Found conflicting mods: lambdacontrols breaks {optifabric @ [*]}
Creating Empty clause ?

Sorry! didn't see your new post.. Thanks, have a great Day/Night! ^^

if "breaks" appears in the error message, just know the mod won't fix it.

Won't fix, I don't want to deal with a deprecated mess, use alternatives: https://gist.github.com/LambdAurora/1f6a4a99af374ce500f250c6b42e8754
