The last video contains the ending credits which is where the music would be. We encountered a content matching issue with the very first video in the series because of the intro (which interestingly did not trigger the German side it seems). What matches and what doesn't is specific to each game, and this isn't something we can really predict. We don't know what will happen until after we upload to YouTube and wait for the video to process.
The only way it could possibly be fixed that I know of would be to mute the video (in whole or just in the part where the matching music plays), but that would mute the video for all regions, not just Germany, and you'd miss Day's commentary as the credits play. D:
If anyone else has suggestions to handle this particular issue, we're all ears!
I'm so very sorry.
