woooooah nice catch! It turns out I had set a switch to turn on at the beginning of that event so that the organ music could play and was supposed to set it to turn off at the end of the event. I forgot to do that, which prevents certain maps from playing their music. It’s fixed now, so you shouldn’t have that issue once 5.0 is released.
Ah, I see. That's a relief. Hopefully Dorian won't be an annoying absurdly-healthed superboss, that shit shown below is just really ridiculous... :/
Also, I SOOO loved the yurilicious happy ending between Mila and Jessica, it touched me in my yuri-feels so well... <3 <3 (It REALLY makes me sad that I have to decline Jessica's wholesome yuri-confession just to proceed [muting the audio and replacing the fight audio with this song from Halo 2 fits perfactly with my sorrow of saying "no" to poor Jessica... T_T
], at least I won't kill her. I'm not a heartless Genocider like Chara from Undertale after all) If you could have it so that Mila could romance Jessica later after perhaps finding a miracle-like cure for her vampirism (yes, they say it doesn't exist, and while Faye's vaccination may have been faulty, it was still a step forward to true vaccination regardless and perhaps reversal so that Jessica and Mila can love eachother normally :) ) or even if it's just romancing her in general without the alternate ending occurring, you have NO IDEA just how happy that'd make fellow yuri-lovers such as myself, seriously...! ^l_l^ ( <happy-tears emoticon of course)
EDIT: I uncovered a VERY annoying issue that occurs once you attempt to get Hunter Rank (HR) 36 and beyond, my current hp/mp goes from this: 
to this: 
so yeah... hopefully this issue is fixed in the next version since this is yet another ridiculous bug i've encountered. *sigh...* DX
