Recently updated from 6.1.6 to 6.2.3 and all DynamicNode() calls now return "System.NullReferenceException: Object reference not set to an instance of an object."

Error happens when trying to load a .cshtml script file directly, not placing it in a template or macro.

I placed this code into a .cshtml file and ran it.

In 6.1.6 it would run just fine
In 6.2.3 it would trow an error (unless loaded though a macro)

@using umbraco.MacroEngines

@{
    dynamic Test = new DynamicNode(1052); //Any Published Node
}

@Test.Name

Is there any setting in the config files that would break DynamicNode?

I Tracked down the problem to the umbraco.MacroEngines.dll - as long as I don’t upgrade this dll, DynamicNode() will keep working. But obviously this is not a good solution so if anyone has any ideas why it doesn’t work on the 6.2.3 version of umbraco.MacroEngines.dll I would be much appreciated.

I took a stock 6.1.6 site, created the test script file and it loaded just fine, then upgraded one version at a time till it broke.

DynamicNode called from a .cshtml file stopped working at 6.2.2 - Is this is bug? Feature? is there a work around?
