Dunno if it's been posted yet or not already, but a rather annoying bug occurs after finishing the "Scrawled Contract" sidequest and what it does is mess up the organization of the bgm. Normally the bgm plays normally when transitioning from the overworld to the town of Mor and so forth, but I noticed that after playing the organ in the church of the Humilem, the bgm linked to the overworld/town of Mor no longer plays for some odd reason. Here's video proof of what I mean:
Said bug also occurs even if I walk out of the village instead of using the teleport function. Strangely, the "Slime Rancher", "Resort area", "Port area" and "Rotten Grove" can replace said bgm and yet it still remains "stuck" on said track when transitioning into the locations shown in the video, hopefully this issue is resolved soon. In the meantime I guess i'll put the completion of the "Scrawled Contract" side quest on hold until said issue is resolved in a patch-fix or some such. (I intend on removing the video once you've seen it so that way it doesn't clutter up my uploaded Youtube videos)
(If it helps, I finished this quest on chapter 3 after entering Fallholt for the first time, also, for some odd reason or another, the journal entry of "Scrawled Contract" doesn't update to say to play the organ after acquiring the "Hymn Sheet" and it only lists it AFTER playing the organ, maybe that has something to do with this bug? Not sure, but just thought i'd mention it regardless: 
)
EDIT: (Found yet another odd bug that occurs if you use the teleport statue found in Crescent Village located inside the snowy Fenrir Glade forest area: 
it's hard to make out at first glance, I know, but you can clearly see the "snowflake effect" occurring here where it clearly shouldn't, it transfers to the overworld and to the town of Mor as well, hope this issue gets fixed as well)
