playerKillPlayer EventCommand no longer firing any commands at all

Description of Issue

I have a few Player kill commands run when a player kills another player, titles, resets their back and a sound to verify the kill.

But at some unknown time/point all these commands stopped working, they have been working for years. Now other event commands are working fine, so its just the playerKillPlayer event.

Is it possible another plugin could be taking over this event and blocking other plugins such as CMI being able to listen to this event? Because whats weird, is randomly worked once or twice ealier in the day and without any changes at all, will not fire a single one.

I do use the premium PvP Manager plugin that could also be listening to PvP kill events.

No errros in console
