Class redirect needs to be specified for this to work.
When changing the name of a module or creating a new module, updating the _API of a class to the new module will cause blueprints based on this class to lose reference
Blueprint no longer has reference to MyActor class and cannot be opened (trying to open causes the editor to crash)
Updating module and API reference updates class/blueprint reference.
