[RMMV] NODEKIT SAYS I HAVE FILES MISSING... WTF?!

This is from a newly created project file, and none of the core js files have been edited. I noticed test games were sluggish loading and now I know why, it was trying to find files it couldn't find.
What I don't understand is:

• I DO possess pixi, pixi-tileset, and pixi-picture js in my libs folder. They are loaded successfully.

• I DO NOT possess these same files with .map at the end. My index file calls for pixi, pixi-tileset, and pixi-picture, but not with with .map afterwards. Here is what I am looking at:

This happens even when all plugins are turned off as well btw. What is a parser error? Is this cause for concern? I can't submit stuff with files missing.
