EDIT: I accidentally posted the topic early.
Logs say there are duplicate mods when none are present.
Solutions tried so far. [Obviously willing to try them again/drop mods.]
>Running in default launcher.
>Running with all non-dependency client-side mods turned off.
>Removing mods with similar names or functions.
>Removing allomancy/feruchemy due to their niche/buggy nature.
>Repairing instance/Reinstalling Instance.
>Tried different levels of RAM allocation.
