I need an explanation.

So, I'm playing in the middle of Tear Drops and look over at the score bar. Mr. Blue Guy to my left has apparently dc'ed early into the song. Might as well do my best to salvage the remains of a song w/o fever, right? As expected, fever animation doesn't show up. I finish the song and I see the score bar. Wait, how did we get near S without fever? I can only get 1.8mil points when I get fever. I also checked the amount of coins I got for an A-grade 1 flame in multi live which checked out at 2000 coins.

This either means that the game glitched and gave fever bonus, or blue guy's points got ghosted out and we got robbed of a potential SS.

Just an anomaly that I had to get out of my system. Happy tapping!
