Can you notice something weird here? I have the "IOSYS - Fascination Marisa" beatmap but it doesn't appear in the "Jump to..." dialog box list.
How to replicate:
1. First, download a map. Any map will do.
2. Add it to osu!'s song menu in any way (I always use Drag&Drop or osu!direct, but I think any will work).
3. Go to the main menu, bring the "Jump to" dialog box up. If you try to search the beatmap you just added, it won't appear in the list.
4. Restart osu!.
5. Now, if you try to search it, it WILL appear.
Hmm, not sure if there's another way to fix it without restarting osu!, but this procedure should be enough.
