Problem details:

I'm not able to download this map, it says downloaded and then imported but clicking the notification doesn't do anything and neither does looking for the map on my own.

When I go into beatmap listing to look for it, the result I get is the one on the screenshot, infinitely loading even though it did say downloaded and imported. If I close the game it will show as undownloaded again.

This has been going on for a while so it probably applies to past versions too. I don't have issues with any other map that I'm aware of and I have no idea what might be causing this. If I had to guess, probably a lazer issue with a very unpopular and old map so no one ran into it.

Video or screenshot showing the problem:



osu! version: Lazer 2024.906.2 (latest)

Yeah I checked on my instance and that's a known bug. The map will actually have downloaded and imported fine, but it just won't show that way on the beatmap listing. It indeed is caused by the beatmap being very old.

2024-09-17 15:35:49 [verbose]: [c3cab] [APIBeatmapMetadataSource] Online retrieval mapped Romantic Mode - Dreams (Elzamxrai) [Normal] to 54 / 141.
2024-09-17 15:35:49 [verbose]: Discarding metadata lookup result due to mismatching hash (expected: 50791b017c9d43382403f343fdb62c77 actual: ac6e971d689e87e12d8c170e1f5b31ff)

is what I get in logs when trying to import it. The short explanation is that we verify the contents of the beatmap to ensure nobody tampered with it to cheat, and in this case apparently the known-good online hash of the contents is not actually correct and thus the game determines that the beatmap must have been tampered with even though it has not.

We've had a possible plan on how to handle these situations for a while now but it hasn't happened yet I guess.
