So, I was going into Stage 6 of my PCB Easy SakuyaB run with seven lives. Had a flawless stage 4 run, and did pretty good on stage 5, too. Felt pretty confident about my chances, which is good because I absolutely detest SakuyaB.
Then I died to Flowery Soul "Ghost Butterfly".
Three times.
Then I had a stupid death on Subtle Melody "Repository of Hirokawa -False Soul-", followed by a death on Cherry Blossom Sign "Perfect Cherry Blossom of Sumizome -Seal- when I know I hit the bomb button before that bullet hit me, and promptly got torn apart by "Resurrection Butterfly -10% Reflowering-" because of the goddamned red butterflies.
Since I never use continues, I figured that I'd switch over to ReimuB and do a practice run of stage 6, since ReimuB's shot type is similar to the shot type I usually have SakuyaB locked into when I'm focusing.
And that was how I discovered that my ReimuB clear has stopped existing for no apparent reason.
