Nativized blueprints cause error in multiplayer

I’m afraid I cannot make this work with the new 4.18 release. I copied the nativized assets from Intermediate\Plugins\NativizedAssets\Windows\Game to Intermediate\Plugins\NativizedAssets\Windows\Server, because I got a compiler warning message about missing assets when building the server. The compiler message no longer occurs, but the server still does not run properly and complains about missing assets :-(. Could you please give me a hint how this is done in 4.18?
