z-wave plugin v 3.0.1.66

Since upgrading to version 3.0.1.66 I get the following error.
Apr-06 13:44:53 Error Calling HSEvent in plugin Z-Wave, Instance :Object reference not set to an instance of an object
Apr-06 13:44:49 Error Calling ConfigDevice in plugin Z-Wave:Object reference not set to an instance of an object

I then have to restart the plugin manually. Is anyone else having this issue?
