I've tried this with a few 4k mania skins that I nabbed online but to no avail. Tried to cut 'n paste the .osk file into the Skins folder, and when I restart osu! it doesn't appear. Tried this with like two or three 4k arrow skins already.
^ if you do have any neat 4k arrow skins though please link them here i've been looking for a few to add to my collection for funsies
