Reply To: I uploaded a song in C3DB, deleted it, reupload, but it’s detected as duplicate
At the moment there is a bug where songs in the C3DB that currently have no attached customs will still trigger the duplicate filter. Fortunately it’s easy enough to work around, and I have done so. You should be able to (re-)upload the song now.
In the future, when you need to fix a custom, you can use your C3U file manager to upload a new version. Find the song in your file list, then select “Upload new version” from the action menu. The rest of the process will look familiar to you.
