Rage mp gets stuck on loading after joining a server

 It gets stuck here and infinitely loads anyone know how to fix this?

While developing my server, I've noticed this more and more lately, especially as I add more resources such as add-on vehicles and scripts, even with a custom gameconfig.xml loaded in. Sometimes it doesn't even finish loading at all. I'm at a loss on how to resolve it myself.
