Driving Dynvars
Driving dynamic variables must be done with caution. If a dynamic variable is being driven, it is crucial that all instances of the same dynamic variable are driven by the same value. Otherwise, clients will fight over which value is the "true" value of the dynamic variable and cause inconsistent behavior. The other caution relates to how driving is essentially a local write each frame, which is expanded on in #Writing/Driving_Delay_Warning.
