Packaging Game Issues

When I package my game, there are a few features that do not work correctly when I launch the .exe file. My game has features such as an objective system which uses blueprint classes for those, a camera that starts a cutscene at the end of the game, being able to read notes and an animated door.

The only thing that does not work is the objective system and I have no clue why it doesn’t. I’ve never packaged a game from Unreal before so maybe I am missing some settings to do with blueprint classes? I’m also not sure if there is anything I can post here to help figure out the problem like a bug report after the game has packaged.
