Which commit has broken this?

[PikuZheng]

I am expected to give more information on Sunday. sorry.

It is currently known that when re-downloading, the "Download Folder" becomes "Format" and the addition fails

[PikuZheng]

If the "Download Folder" is not default, this error occurs when the retry button is clicked after the download fails.
I did not find the reason. Sorry.
