I've been trying to complete the "Dynamic place creation and saving" tutorial, but i still get this error Game CreatePlace received and error: HTTP 0 (HTTP 400 (HTTP/1.1.400 TemplatePlaceNotInUniverse)).
this error only appears in online mode
This means that the template place you are trying to access (create) is not part of the universe that the game for which your script is running in is in. You might want to try checking your IDs in your script, as transposed numbers can cause this issue.

I restart all over again, and success, I finally finish the tutorial
