When Packacking Project many actors are missing aswell as materials.

As seen in the image when i package my project there is just so many issues that do not appear if i do a quick launch or play in editor. It is only a problem for packaged projects.

It is my first time using world partition for a project so it might be related to that ? I packaged for windows only and i got some error messages regarding the VRM4U plugin but i would be surprised if those would break everything that has nothing to do with the plugin.

I don’t even know where to start so if anyone has any tips or things i could check i would be glad.

Edit: I did not change anything in the packaging options and tried dev, and shipment mode. Is there anything i need to adjust for worldpartition projects ?
