Yep, it looks like we're getting a player with a NULL state somehow, which is crashing when we try to convert that into a variant for sending over the bus. (1) we should sanitize our inputs better, ie modify the state property setter to disallow NULLs. More importantly, (2) we need to figure out where this NULL state is coming from.
