Hey everybody! Playing RB:Blitz like a mad man recently and I just noticed this.
This really surprised me out of left field, but when I played "Ron Wasserman - Revengers", seems like the game couldn't connect to Rock Central for some reason, and disconnected me from the game, bringing me back the main menu, and making me wait for "Discovering Download Content" process. That made me waste time and, more importantly, coins from the power-ups I used.
I tried the song again, thinking it to be just a wierd hiccup in my internet connection (I'm uploading some random video to YouTube, my router dies whenever I do that), and yet again the same problem persisted. From 3000 coins, I lost most of them during these two attempts. Mostly my fault for doing it with power-ups active, haha!
That's when I decided to play a different song, one from the official RB DLC releases (30 Seconds To Mars - Attack), and it worked perfectly. Connected to Rock Central, and got some paltry amount of coins for doing a new song, etc.
Was just thinking, since the RBN song was pulled, maybe that had something to do with it? No official leader-board ranking and so on maybe, so the game just struggles to connect. I'm going to play some of the other songs I got that have been pulled off the marketplace and see if it really is that issue, haha! (With no power-ups active of course, don't wanna lose my coins).
