Sorry this took so long! I got quite burnt out after debugging for weeks and it still not working, so I ended up putting the project on pause for a while. That being said, I finally got it working, and I'm even working on 2.1 now that I have a little more experience playing on a couple different Origins servers! Happy sculking!
