#30 AttributeError: 'NoneType' ...

[Pablo Castellano]

I was playing Jimi Hendrix - Spanish Castle Magic several times.

One of the times, when I finished I saw some unusual message in the middle of the screen. I could just read "NoneType" because it disappeared quickly. But the game didn't crash. It happened also the next time I finished this song.

When I exited normally, in the console was:
