Due to the way scenarios work they can not be directly loaded on our servers but do not despair you can still easily play them on your AleForge server. It just requires a couple of steps.
- Stop your server
- Open your Factorio Game
- Go to Play->Scenarios and select the scenario you want to play on the server
- Immediately save your game and exit.
- Find your save file at %APPDATA%\Roaming\Factorio\Saves.
- Upload your save using the panel's file manager to the root of your server
- Change the Save Name to load in Configuration -> Startup Parameters and make sure to save the changes
- Start the server and your scenario will load.
