Plex binding returning strange error

My plex rule to update my hue based on the progess being updates has broken - I’m getting loads of errors like this:

java.lang.ClassCastException: null

PlexLightsRule looks like this

rule "PlexLightsRule"
when
	Item PlexLoungeRokuProgress received update
then
//	logInfo("Updating hue")

		var amount = (PlexLoungeRokuProgress.state as DecimalType ) 
		var DecimalType hue = new DecimalType(120D-(amount * 1.2D))// 0-360; 0=red, 120=green, 240=blue, 360=red(again)
		var PercentType sat = new PercentType(100) // 0-100
		var PercentType bright = new PercentType(100) // 0-100
		var HSBType light = new HSBType(hue,sat,bright)
		sendCommand(Lounge_Light_Hue_Color, light)			
end

and the item PlexLoungeRokuProgress looks like this:

Dimmer PlexLoungeRokuProgress “Progress [%.1f%%]” {plex=“Plex4224D4001173#playback/progress”}

All of this worked really recently so I suspect there might be an issues with the latest plex binding 1.8.1. Has anyone else encountered this?

A restart fixed it.
