Yup, it's still happening. It's obviously something to do with the teleport statues I think, but not 100% sure if this is the case since, as I was done all contracts (sidequests) I was continuing along with the main quest, though the annoying issue still occured unfortunately
Well obviously since I progressed quite a bit through the story before the recent version, though I continued only after the latest version was released and had the "Scrawled Contract" on hold due to the aforementioned issue regarding the bgm and I didn't have the annoying "everlasting falling snow" issue on the screen either, at least since I didn't use a teleport statue to instigate the issue of course.
