I connected with Mohammad Mossa(known as WizardCell online) recently, after discovering his extremely helpful #notGDC video linked below. For those struggling with Replication or some grey areas in multiplayer functionality, this video is incredibly useful and educational.
I wish a resource like this was available when I first started my journey of creating BvB. Along with other fantastic information available on his website!
