Now I've made a change to my music file, and the build is being canceled whenever I try to run or export it. This wasn't happening before in version 4.1.2, but now I can't run the game. I've tried clearing the cache and everything.
Thanks Levi! I've just released 4.1.3 which includes a few more bug fixes and make sure this error appears correctly again :-) The error message now also includes a link that you click to jump to the scene that has the missing background
