Same issue here, New game, instead of copyin' live one i just changed the name folder then put aki in.
no issues on server logs,
On both error and traces the last line are this:
0.12.10.1.11661|Info|backend|---> Request URL: https://127.0.0.1:443/client/game/start:
0.12.10.1.11661|Error|backend|<--- Error! URL: https://127.0.0.1:443/client/game/start, responseCode:0, error text: Unknown Error

`Original (Live) version should still be present and it should not be edited in any way.` Is this really necessary now? had no issues on 10532.
