NullReferenceException: Object reference not set to an instance of an object

Hello,

Getting this spamming the console since yesterday. Any ideas for fix?

Tried a unload and reload of the plugin. Messages still persisted. Did a /rnpc killall in game, error messages still persisted. Did another reload of the plugin in console and the error messages stopped. 

Changed Status from Pending to Closed

Changed Fixed In to 0.4.0
