An item with the same key has already been added.

[MegaPiggy]

I made 2 mods with different names and set the mod merge setting to MatchingModName. I don't want them to merge, but
when I boot up the game it will break with this exception.

ArgumentException: An item with the same key has already been added. Key: MegaPiggy
