When i try to preview my game this message pops up:
Assertion faliure: Project model unavailable
at Error (native)
at assert2 (http://localhost:50000/preview_prelude.js:16:10
at Runtime.loadProject (http://localhost:50000/preview.js:151:41
at XMLHttpRequest.xhr.onload (http://localhost:50000/preview.js:412:11
Subsequent faliures will be logged to the console.
After that so does the loading icon never pop up so the preview never starts.
What can i do to make me able to preview the layout?
