I'm gonna be honest with everybody, I don't know how to fix your problems, I only uploaded this, I did not fix it. Originally, an old friend of mine uploaded this to his workshop, but he deleted it, so I got permission to reupload it. So, I'm sorry but I can't fix any of your technical problems with this addon. So, if anyone is willing to make a cleaner version of this addon and add the Rock and Pink Pikmin to this, be my guest, but don't ask me for any help anymore. The only advice I can give you is that if you're having problems, then uninstall this addon, exit out of the game, then reinstall it again, that always worked for me.
