Work in progress

Testing checklist:

• yes I tested this in a runServer environment, and therefore won't make leaf cry
• yes, I actually connected to that server and verified it worked and don't need to have my kneecaps removed
• yes, I also tested the built jars manually outside of the development environment, because problems sometimes don't show up inside the dev environment.
