Sorry, I should probably elaborate more on this…
The facts:
- Project was cloned and ‘Convert In-Place’ from 4.2 to 4.4.1
- Project is entirely blueprint based, there is no code project associated.
- The application works correctly in PIE and Standalone.
- There were a lot of other errors related to missing assets, however these have been fixed.
- I have no idea where that function is called.
