Problem Details:
You can get unsubmitted maps get any preview you want, and I found out how
Look at the number of a map (you want a thumbnail of) for example, 110547
Then get a .mp3 of the songs you want to map, and give it those numbers to the name. For example 110547 song.mp3
Open it in editor and do a few things (set metadata/timing and put a circle) (Not sure if needed, but I only noticed it after this)
Then you'll see the map has the incorrect thumbnail
I had this happen quite a lot, and maybe if this gets fixed, all wrong issues about it get fixed, as it strangely enough is tied to the beatmap number of the folder
