So I've had this happen to my game a few times, as reported by a couple of users and just then now when I was testing a new apk.
On first time launch, the game hangs at the loader screen. It will start loading, so part of the progress bar fills, but then stops moving. A restart of the program seems to fix it and then the problem doesn't reoccur.
Wandering if anyone else has encountered this? I wonder what causes it.
I don't think I'd be able to reproduce it in a separate cp3 file, so don't know that filing a bug report would be any use.
This was on stable build with the c3 runtime on Android.
