Conflict with FlashlessBang plugin

I run a PVE Server and need to run the plugin FlashlessBang to disable flashbangs on my server as some players come annoy and grief players with these items.

But when this plugin is loaded no NPCS spawn from your NPC Grenades. Only once I unload the plugin the NPCS will spawn. Could we get a fix for this?

Sorry for the delay You would need to contact the plugin makers of FlashlessBang and request they ignore items spawned by other plugins.
