[08:50:32] [Server thread/ERROR]: Nag author: 'Spliterash' of 'MusicBox' about the following: This plugin is not properly shutting down its async tasks when it is being shut down. This task may throw errors during the final shutdown logs and might not complete before process dies.

[Spliterash]

NoteBlockAPI call sync task when my plugin disabled, so i can't do anything, because im need destroy all my player songplayer

[mibby]

Is there no safer way to do this? Should this be reported to NoteBlockAPI instead?
