I think there is an error of inattention in Gdevelop 5 code about the music
Here is what I put : prntscr.com/ij4v6g
Here is what I get : prntscr.com/ij4vbm
Since it’s not a full release, there still lot of bugs, so I don’t know if there is any interest of sharing all of them, but this one can be boring to code tbh haha
Fixed!, thanks
