Trying to run my games server, get an Assertion Failed error...

So basically, i converted my project to source build so i could start working on dedicated server stuff. I built the server, it compiles with no errors. When i try to run it i get the above error.

I tried doing the same to the ShooterGame example code, again it builds for server with no warnings or errors, but running the server gives the same error.

So does anybody know exactly what i’m missing or doing wrong here?

If your not using it, dedicated servers need cooked content.

the content is cooked but i’m still receiving that error.
