If the API login (and thus user set) completed between `load` and
`LoadComplete`, the re-fetch on user change would not yet be hooked up,
causing an incorrect default background to be used instead.
Of note, moving this out of async load doesn't really affect load
performance as the bulk of the load operation is already scheduled and
`LoadComponentAsync`ed anyway
Was added in cc76c58f5f without any
specific reasoning. Likely not required (and will fix some storyboard
elements inside `.osu` files from not being correctly saved).
After way too much time investigating this, the encoding situation is
not great right now.
- Stable sets the "default code page" to be used for encoding filenames
to Shift-JIS (932):
c29ebd7fc5/osu!/GameBase.cs#L3099
- Lazer does nothing (therefore using UTF-8).
When importing to lazer, stable files are assumed to be UTF-8. This
means that the linked beatmaps don't work correctly. Forcing lazer to
decompress *and* compress using Shift-JIS will fix this.
Here's a rough idea of how things look for japanese character filenames
in current `master`:
| | stable | lazer |
|--------|--------|--------|
| export encoding | shift-jis | utf8 |
| utf8 [bit flag](https://superuser.com/a/1507988) set | ❌ | ❌ |
| import stable export osz | ✅ | ❌ |
| import lazer export osz | ❌ | ✅ |
| windows unzip | ❌ | ❌ |
| macos unzip | ✅ | ✅ |
and after this change
| | stable | lazer |
|--------|--------|--------|
| export encoding | shift-jis | shift-jis |
| utf8 [bit flag](https://superuser.com/a/1507988) set | ❌ | ❌ |
| import stable export osz | ✅ | ✅ |
| import lazer export osz | ✅ | ✅ |
| windows unzip | ❌ | ❌ |
| macos unzip | ✅ | ✅ |
A future endeavour to improve compatibility would be to look at setting
the utf8 flag in lazer, switching the default to utf8, and ensuring the
stable supports this flag (I don't believe it does right now).
Rather than creating a "corrupt" realm file in such cases, the game will
now refuse to start. This behaviour is usually what we want. In most
cases a second click on the game will start it successfully (the
previous instance's file handles are still doing stuff, or windows
defender is being silly).

I'm not actually super sure as to what the exact mode of failure is
here, but it's 99% to do with working beatmap cache invalidation. Likely
this can be even considered as another case of
https://github.com/ppy/osu/issues/21357, but because this is a one-liner
"fix," I'm PRing it anyways.
The issue is confusing to understand when working with the swap scenario
given in the issue, but it's a little easier to understand when
performing the following:
1. Have a beatmap set with 2 difficulties. Let's call them "A" and "B".
2. From song select, without ever exiting to main menu, edit "A". Change
the difficulty name to "AA". Save and exit back to song select; do
not exit out to main menu.
3. From song select, edit "B". Change the difficulty name to "BB". Save
and exit back to song select.
4. The difficulty names will be "A" and "BB".
Basically what I *think* is causing this, is the fact that even though
editor invalidates the working beatmap by refetching it afresh on exit,
song select is blissfully unaware of this, and continues working with
its own `BeatmapInfo` instances which have backlinks to
`BeatmapSetInfo`.
When editing the first of the two difficulties and then the second,
the editing of the first one only invalidates the first one rather than
the entire set, and the second difficulty continues to have a stale
reference to the first one via the beatmap set, and as such ends up
overwriting the changes from the first save when passed into the editor
and modified again.
