As reported (very poorly) in
https://github.com/ppy/osu/pull/28991#issuecomment-2331854970.
I believe this is a total edge case and is mostly visible on dev due to
some beatmaps existing on `osu.ppy.sh` and not on `dev.ppy.sh`, but I
tend to agree in general that these types of failures should not be
firing very loud error notifications; logging to network and disabling
the button with a tooltip adjustment should be enough.
The more proper way to do this would be to address the underlying issue,
which is https://github.com/ppy/osu/issues/29546, but let's do this
locally for now.
