The control panel never behaved like this before. What's going on?
Not quite sure. I noticed that the actual .ogg files are getting renamed. Was that intentional?
I should also probably note that Add-Ons are working fine.
EDIT: Alright, here are some screenshots of the bug happening:
Uploading (FTP client, viewing the server):
Control Panel (as it's renaming them):
Afterwards (viewing the server again):
I have another batch of music with _-_, uploaded after this that have not yet been affected.
