Did you manage to solve this problem? I have the same issue, all packages are set to copy to distribution points. Access content directly appeared in deployment options but every time I select it, it reverts to download content after opening deployment settings. What's worse, when it is set like this task sequences crash frequently (but not all the time, configuration is ok) with this error:
Failed to run the action: Install Application.
The RPC server is unavailable. (Error: 800706BA; Source: Windows)
