Got it working now thanks for all the help
Did:
- Open with sftp
- upload the known working save (or use an existing id)
- Verify that correct save game id is set in configuration in amp
- Start the server
- Sees that game files updated
- Loads and plays 30min
- Restart server and verify game progress is still there
there was probobly some problem with it thinking save id was empty and then creating new saves each time.
