[File Manager Bug]

I'm currently trying to add custom advancements to my server using datapacks.

But for some reason when I upload the file adv1.json it doesn't upload. Uploading root.json works but adv1/adv2/etc doesn't work.

adv# isn't in the disallowed file names please fix this if it's a bug or include it in the list if it was on purpose.

[NoteBlockAPI]

I'd like to play noteblock midi fiules on my server, NoteBlockAPI, PlayMidI,etc, would be used a lot on mining/pvp servers.

If you know a noteblock plugin that's already in plugins list, plz tell me!
