I thought I had responded to your post, —
After some testing, I believe it was the music file type that was causing issues. Once the game was running without preloaded sounds, the game would reset when playing the sound played by button presses in my project. After converting everything to mp3 audio files, I could preload sounds without problems.
However, playing music has a MAJOR effect on performance, so now I am preloading the music files as sounds. This makes a longer initial load time, but the game is playable after that.
I had seen your post before, however your issues may be different from mine. I am using the r98 stable build of C3.
