~when sending a redstone signal to a Jukebox playing a custom music disc, the custom song stops playing and the assigned vanilla disc starts playing (assuming that the disc lost its NBTs). Same happens with the jukebox/chest combination, it works for a while, but then the discs lose their NBTs and the playlist doesn't work anymore...~
~there were no errors or warns on boot neither when those bugs happened. My server's 1.16.5...~
UPDATE:
I found out the problem was the Redstone Jukebox mechanism from Craftbook 3...
I disabled it, but maybe you should add either in the plugin description to disabled it or to find a way to "support" it...
