I have added CodeChickenCore, And that problem has been solved, thanks! But when I tried to launch it again, forge showed me this:
Forge Mod Loader has found a problem with your minecraft installation
mods and versions listed below could not be found
gilded-games-util : any
The file 'logs/fml-client-latest.log' contains more information
I did what you told me but I couldn't find anything to solve it.
this is the modpack I currently have: https://www.dropbox.com/s/yei3i0pvhyjcfol/modpack.zip?dl=1
i hope you know how to fix this, thanks,
