Assertion failed gdefaultmaterials

Hello everyone i followed this tutorial on how to build ue4 for a dedicated server and when i compile from visual studio nothing fails until i try to run the .exe’s both the server and the client error out and immediately shut. Though packaging it from in engine works fine. This is the error i get from the server Assertion failed: GDefaultMaterials[Domain] != nullptr [File:D:\engines\epic\UE_ - and the client has the same first two lines assertion failed, but not the rest.

Alright so it seem i misunderstood the dedicated server setup i was putting the server.exe in the wrong folder if anyone else makes this mistake :stuck_out_tongue:
