Multiplayer rooms are missing their scores

[TTTaevas]

(note I'm only talking about the type of rooms where players play against each other in real time, not the type of room where players have 7 days to play specific maps)

Up until somewhat recently, on the page of a room, the beatmaps (the items) that were played in that room would be displayed
Now they simply do not display anymore, and the "Map Count" remains on 0
Example: https://osu.ppy.sh/multiplayer/rooms/413097

Similarly, on the side of the API, the endpoint to get scores from a room's item doesn't seem to work anymore, but it's important to note the undocumented endpoint that is used to list a room's items does work, its playlist array has all the items you'd expect it to have
What I mean by "the endpoint to get scores from a room doesn't seem to work anymore" is that it'll always give this as a response: { params: { limit: 50, sort: 'score_desc' }, scores: [], total: 0, user_score: null, cursor: null, cursor_string: null }

So there must be some issue going on with playlist items

I think these rooms don't have their previous score entries migrated to score_links? @nanaya @peppy

[nanaya]

It was some migration failure before (somehow score links aren't created properly) and then the remaining scores got wiped/archived sometime in jan.

I'll track progress in here.

So far I have removed all links to old solo_scores.

I'm currently working on re-importing these scores with ranked=0 so they can be restored in the leaderboards.

All recoverable scores have now been reimported!

Thank you very much!!
