Animal Well (PPSA22520) checks for its save with a CREATE2 mount it never
unmounts, then saves with a second mount of the same directory. That
mount returns BUSY, and the title keeps using the first mount point for
sceSaveDataPrepare, its save file and sceSaveDataUmount2.
sceSaveDataMount3 cleared the result before its checks, so the save was
written to "/save" in the game folder instead of the save directory, and
the first mount was never released. The result is now written only when
the mount succeeds, as shadPS4 does.
sceSaveDataMount3 with SCE_SAVE_DATA_MOUNT_MODE_CREATE2 opens a save that
already exists, so its mount status is 0 rather than CREATED, as shadPS4's
savedata.cpp reports. A CREATE mount still reports CREATED.
