NodeCanvas destroyed after returning from Play Mode #12

Unity version: 5.1.2p3

If I open the Node Editor, enter the Play mode, stop the Play mode and click on the Node Editor window again it stops responding and I get a lot of repeated errors in the console with the following error:

MissingReferenceException: The object of type 'NodeCanvas' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

Strange, last time I chcked the canvas was simply unloaded, which is a minor issue... Thanks for the report, I'll take a look at fixing that today:)

Adressed that too in my latest commit (2dd6eb8a3e49fe9e1853685282cac4d98dd06522) next to other things, simply added a check for the canvas;)
