I am running into an issue while using the latest beta. When renaming files I will randomly get:
“Mp3tagTmpFile-Z8fF2z” couldn’t be moved to “Believe (2003)” because either the former doesn’t exist, or the folder containing the latter doesn’t exist.
It's not clear where the MpsTagTmpFile-Z8fF2z is coming from. It seems to replace the filename with that only inside mp3tag. Both the actual file and the directory exist as it's already renamed other songs in the album. To fix this I have to remove the album and re-add it then run rename again.
