I believe this is tied to this plugin, but fireworks will light, but never go off. The fuse just sits there lit forever. I have both the CCTV and Devices Always On enabled.

Please o.unload LightsOn and see if the problem persists. If it does, it is not the plugin. I do not directly code against fuses so it would be unlikely the plugin. Are you running other plugins that might affect the fuse?

I'll test it out and see, and I don't think there should be any other plugin that would affect fuses, but who knows.

Pretty sure its a Vanilla thing since last update to combat server lag caused by multiple fireworks going off at once.

Okay, I think it was a client issue cause I didn't turn anything off and fireworks worked fine for me. Sorry for passing it along before checking myself!
