So, i recently tried to get chemcraft, and got an error(Made a thread about it) and i was told to contact the creator of the mod. So instead i tried minechem which then gave me this error.

After i got this error i thought maybe it was my forge version because on the website it showed the version to use. So i installed that version and still got that error

EDIT: I figured out crash error, and added missing mod.
