Well it would seem turning on Caterpillar, reducing the maximum party to 1, and then turning caterpillar back off in the config application fixes the error. Not sure if this is related, but I tried adding the Global Switches and Variables script as well which resulted in my game not going anywhere after I clicked login.
Course, things between RMX-OS and me have been going oh so smoothly ever since I tried using it... /sarcasm
