I wrote some code up today between classes, it's the start of a text RPG game (Or maybe some type of software client? I don't know yet) and right now the code is messy because i'm too busy manually checking other stuff and swapping out code to get language file loading to work right. It's becoming a nightmare to work on using the Chromebook I have to use. Maybe pulling it up in Pycharm at home will allow me to fix it up and make it pretty? 
Essentially i'm using the info command in sys_control to load different data, and python doesn't like loading values from files to lists for some reason.
(If anyone knows how I can get this working, please let me know, I have been working on that for the past two hours.)
