I believe the issue is the same as that CableComponent question you found. What probably is happening is that the game module is loaded before the minimap module is. You should try what is suggested in that CableComponent answer. I’ll explain it in more detail:
- Go to your UE4.16 install folder and then the plugin folder. For me this is C:\Program Files\Epic Games\UE_4.16\Engine\Plugins\Marketplace\MinimapPlugin
- Open MinimapPlugin.uplugin with a text editor
- Where it says “LoadingPhase”: “Default”, change Default to PreDefault
- Try to package the game again
