I was creating a farm arena to make it easier to get a Miner badge, but I didn't want to use music that already existed. I wanted my own music. I found the music of Fearofdark - The Coffee Zone on youtube, did everything exactly as it was written on the wiki, and the game simply did not see the txt file with the Base64 code. I wouldn't just say he doesn't see it, the game crashes for unknown reasons. And it's not just that I can't upload my music, I can't even save it. please note this shortcoming.
