Infinity Blade asset warnings causing failed packaging

I was going through the Unreal online multiplayer tutorial on youtube. Everything in the game itself is working fine, but when I go to package the game I get “File too long” and “asset not saved for export” warnings in the package log in regards to the Infinity Blade assets. It also seems to prevent the packaging process.

I found another discussion on here that seemed relevant discussing the “asset not saved for export” issue being fixed by toggling the event driven loader in the project settings, but when I went to check for it, I could not find the option. (was sent to Edit->Project Settings->Packaging)

Just trying to figure out why I am getting the warnings in the package log, and what can be done about them to complete the packaging process. Would not mind also getting the location of the event driven loader toggle so I can possibly test it.

If more information is required please ask and I will provide what I can.
