Standalone game - Warning: Can't find file '/Script/MyEditorPlugin'

Hi there,

I have encountered a weird behaviour with an engine plugin when trying to run a level with standalone game option from the editor and was hoping someone would know more about it. I have the following setup:
An engine plugin that has two parts - editor and runtime - MyPlugin.uplugin

"Modules": [
    {
        "Type": "Runtime",
        "Name": "MyPlugin",
        "LoadingPhase": "PostConfigInit"
    },
    {
        "Type": "Editor",
        "Name": "MyPluginEditor",
        "LoadingPhase": "Default"
    }
],

The runtime part defines some classes and their logic. The editor part defines a custom blueprint node which inherits from UK2Node_EditablePinBase and operates with one the classes from the runtime lib. Now, when running the game with “Play in Editor” everything works fine and the custome node gets called. However, if I run the game with “Play in Standalone game” in the same level, the custom node does not get called. The warnings I get in the output log are:

Warning: Can’t find file ‘/Script/MyPluginEditor’
LoadErrors: Info Failed to load /Script/MyPluginEditor.K2Node_MyNode Referenced by EdGraphPin_5463

I figured it might be something to do with serializing - the Standsalone game cooks the game on the fly, but only got so far.
