The packaged version does work. I can’t reproduce it, even by following the tutorial step by step. Can you confirm that the above screenshots are fine (profile settings) ? Did you try this on 4.13.0 ?
I’m still trying to understand the modding limitations. My game is open-source, doesn’t depend on a custom engine, so people could just download the sources and build it. I don’t understand why they would have to do a release themselves, isn’t the asset registry enough to generate a mod ?
