Hi there! Thank you so much for the lovely comment; such praise and knowing you enjoyed the game so thoroughly truly does mean the world to us both. We sincerely hope you continue to enjoy LOVE BAKUDAN, even in the future! ♥
That's unusual about the missing CG's, though. We had one report about this around the time the patch was released, though that was to do with a single missing Himeko CG, never about the books. Quite strange...we'll do some deeper digging into it on our end, but in the meantime, have you tried skipping through the routes with the missing CG's a second time using CTRL? It could trigger the unlocks once you pass the missing CGs, but it's hard to say when bugs are involved. So sorry for the late reply, but again, thank you very much for your kindness!
