Screen (Window) Size Changed Randomly

Morning everyone! I'm freaking out, and I'm hoping someone can help me out here. I was working on changing the screen width size with Yanfly's Engine Core plugin. At first it seemed to be just fine, so I left it where it was (can't remember the exact dimensions). After that I started messing with the Gauge Swap script, and now when I run the game the characters are all resized, the window is resized, and the actors overlap each other because of the narrow window. I've tried going in and resizing the window in the plugin, but it's not working. Any ideas?

Update: Here's the link to the Core Engine Plugin.

The other plugin is just the Community_Basic plugin, but I can't find a direct link to it anywhere. If the Admin need me to copy and past the code in here, I will gladly do that.

Could you edit your first post to include links to both plugins. That way, if anyone needs to check something before giving advice, they don't have to go hunting.
Thanks.

Thanks for the reply, and sorry Sorry for the delayed response on my end. I will see if I can link them when I get to my computer after work.
