Hey hungrykitten,
Looks like there is a copy error in your plugins which is preventing them from running your game (Unexpected token u in JSON). This usually happens if there is an additional token or character in the plugin itself that disrupts the execution of the code. As one of these errors is with Core Engine and all other plugins in the suite are dependent on it, the entire thing is not compiling and spitting out these errors. We recommend sending a copy of your RPG Maker project to our email (myth.atelier@gmail.com) and we can sort it out for you as this type of error is a little annoying to troubleshoot over forum posts. For the subject line of the email, just mention that it is you (hungrykitten) and we can follow up with you there.
Thanks,
MythAtelier Team
